Nope, converse it very frequent. Wrt. to former FE packages, I'd say
it's the "rule".

Consider the rpms can differ internally (may use different paths,
different compilers, might have different deps etc.)

yes, f8 is not safe against rebuilding from the same spec:

# fedora-rpmvercmp 
Epoch1 :0
Version1 :1
Release1 :1.fc7
Epoch2 :0
Version2 :1
Release2 :1.f8
0:1-1.fc7 is newer
