Yeah that can happen - basically when you have all sharp edges being filleted all at once, the fillet mechanism will basically know up front that there will need to be a corner patch built at the spot where the fillet surfaces come together.

If you have some pieces already filleted and then try to fillet more ones that are colliding into those with the same radius, you basically have a lot more little surface pieces involved and that makes things more complex. It will end up trying to do things like building fillet surfaces between some of those already existing fillet surfaces rather than knowing right away to do corner patches instead.

So if you want to put the same radius on everything it can be good to do it all at once rather than some pieces at a time. If you're doing things with different radius values then do the big radius values first and then the smaller ones after.
