I don't get it either. In vitro research shows bartonella easily becomes resistant to rifampin
https://pubmed.ncbi.nlm.nih.gov/27667026/
rifampicin is known to be relatively easy for bartonella and other bacteria to develop genetic resistance to - yes - but that's why its is pretty much always paired with another antibiotic - Dr M for instance always uses it with Clarithromycin.
they do this as its shown by the same kinds of trials to virtually eliminate the chances of bartonella producing genetic mutants that are resistant to 2 antibiotics at the same time.

I suspect "end up being effective when continued for longer" means you eventually try to treat another infection, and then somehow the bartonella goes away.
not sure - there are many people on the breaking down bartonella facebook group who treated with him and only used clarithromycin and rifampicin and got better - so they didnt target other infections intentionally - but its possible that those drugs were treating more than bartonella - but he didn't change it up to target something else as other LLMD's sometimes do
so it really does seem like - for a decent portion of the population with bart - the bacteria are not resistant to rifampicin at the start and do not become resistant during treatment - but are just slow to respond to abx treatment and yet that same treatment if maintained or increased is eventually effective.
this slow response just seems to be a theme in bartonella - not only with rifampicin - but with many different drug approaches - i did months of doxy, azithromycin and rifampicin and had only mild improvements - before stopping due to raised liver enzymes -
later i learned that this pattern is common in bart during treatment because the liver is infected - and the enzymes go high before clearing the infection and then come back down again - so it was actually a sign i was on the right track
so i think its more likely that this slow just a common feature of its pathology
something that is not much publicised is that rifampicin is also surprisingly effective for borrelia - and even borrelia persister cells - at least as effective as most 1st line borrelia drugs in some in vitro trials - so none of these treatments are really targeted to a single infection.
so it seems most people with problematic Bart - also have lyme and vice versa - certainly a quick survey of people on here would tend to agree with this
and i guess it kind of depends on what model we have in our heads of the nature of the disease - Dr M specialises in bart - and seems to be going at it as if its mainly a single infection with bart leading - while other LLMD's like Dr J believe its really always a multispecies infection with around 12 different infections in each host by the time they are very ill.
as you say - it could be that some people are able to recover if one main infection is targeted - and perhaps some overlapping infections are also reduced by antibiotics effects overlapping.
