You, sir, have come across
the golden nugget of Active Surveillance. Not everyone can/does understand this...or many men understand this concept too late. The pure emotion of "the big-C word" can be difficult to overcome. But I think you have got one foot into the door of knowledge.
Allow me to
re-state for you what the data you quoted above says: If you are in the well selected favorable-risk category to begin with, it makes NO DIFFERENCE in cancer outcomes whether you pursue immediate treatment (any variety) or to pursue Active Surveillance. NO DIFFERENCE. That's just another way to say the exact same thing you quoted. I’m going to re-state it again, below, in
different terms that I'm fairly confident you’ve also already heard elsewhere but possibly didn't understand in this light...but let this "NO DIFFERENCE" point sink in for a minute.
While it sinks in, I’ll take a paragraph to address your question about
whether AS is “no decision.” No.
Active surveillance is a proactive, prospective therapy to measure the pace of the disease progression (or lack thereof) by regular monitoring AND instituting treatment based on pre-defined change in the monitoring results. It is deferring treatment with curative intent until treatment is needed…if it is ever needed. For men in your situation, over the long term, aggressive treatment is ultimately needed about
50% of the time, but more importantly it is NOT needed about
50% of the time. But as you can see, those who move to treatment have the same cancer control success rates as those who sought immediate treatment. OK, that answers your “is AS ‘no decision’” question…and I believe I’m not telling you anything you haven’t already read or been told…but maybe it is crystalizing more.
Now, back to the results you’ve posted (and there have been several studies from US and others with the same conclusions as you quoted, above)…I’m going to re-state the study's results in yet another way, which again, I believe you’ve already heard and may only now be crystallizing in your base of knowledge.
First, I'll ask you to digest this important point: Active surveillance DOES NOT guarantee that your cancer will NOT progress and that you will never die of PC. It is ABSOLUTELY NOT A GUARNATEE. It
does progress in a very small number of men. Even “well selected” men. But guess what…”well selected” men who choose immediate treatment instead of AS are also not guaranteed that their cancer will not progress and that they will not die of PC. It
does progress in a very small number of those men, too. And guess what…progression/death happens at the same rate in both groups (check the data
you posted for the rates).
There is a very small percentage of men in the “well selected” category who go on AS will ultimately progress and die (even after they do pursue deferred treatment), and a similar very small percentage of the same cohort of men who choose immediate treatment who will have exactly the same outcome. It doesn’t matter. These cases will create the anecdotal cases of men—very small numbers of men—who started out with favorable-risk cases but unfavorably progressed...some will have pursued immediate treatment, others will have pursued AS. Of course, these anecdotal cases make us uneasy, but their small rates of occurrence are the same, immediate treatment or deferred treatment.
OK. I’ll say it again in another way that you have also heard before, but perhaps didn’t understand in the same way as you might understand it now. For the “well selected” group of favorable-risk men, there is no benefit to immediate treatment. No benefit.
Here's how
you wrote it:

There were no statistically significant differences between the groups of patients with regard to either metastasis-free or prostate cancer-specific survival.
Let that sink in.
Have a good appointment with your doctor…he sounds like someone who will support you making your own informed (rather than purely emotional) decision.
