So will bitbake build again the same recipe (because I've built from the
same one before) with lower PV, just because it _still_ has the highest
DEFAULT_PREFERENCE and it's desired version (but still lower PV because
of hash, then before)?.

Maybe I had not enough coffee today, but I still don't understand it,
sorry, maybe someone else can comment?
