I don't see any spontaneous recentering after that, so a reproducible
test case will be appreciated. Maybe something that makes the
difference hides behind "work with Emacs for a while", I don't know.
Doesn't this mean that you need a way to hook buffer text changes?
Hooking processes is not necessarily what you want, since a process
filter could eat up the output completely and not show it in any
window, in which case follow-mode shouldn't be bothered. Right?

Ask Alain how easy that is.
I'm telling you: this is the tip of a huge iceberg. The display
engine was never designed to handle windows whose redisplay depends on
other windows.
