I'm pretty sure Markus' post claiming that it's not a bug and was only bad luck resulted from a quick check of the programming code. My theory is that it was only a surface check where he looked at the frequency with which these incidents are coded to happen. And I believe him that it's not an issue at that level.
The problem is, of course, that I would think most bugs in a game as comprehensive as OOTP arise because of interaction between different features coded into the game. So the concern is that while the top-level instructions seem reasonable it's still possible that there's something deeper and harder to find going on so that the fights really will be too frequent. And that's the kind of bug that lingers and can't possibly be checked in two minutes. Hence the concern.
I also would hope that Markus sent out a quick note asking people to check fight frequency in their beta tests.
Oh, and also of course he needs to make league prestige an editable field. But only for Ksyrup and Hell Atlantic.
