Conflicts vs Obsoletes

This is against an old rpm (4.0.2) but I think this behaviour hasn't changed
in a while.

If I have a directory with bash.rpm
and someone builds newbash.rpm with Obsoletes: bash.rpm
things works as expected: 
rpm -U newbash.rpm 
removes bash.rpm

Now, unless something very wonoky happened, I think I think I saw
rpm -U bash.rpm succeeding (the files don't conflict).

Is that possible/normal?

In that case, I put both Conflicts: bash.rpm / Obsoletes: bash.rpm
in newbash.rpm?

But if I do that, rpm -U newbash.rpm should still work, however, if someone 
tries rpm -U bash.rpm, should it just be a no-op that won't cause an error,
or would it try to install bash and then fail due to the conflict?

Yes, I can build dummy packages to try all this, but at the same time I want 
to make sure I understand expected (not observed) behaviour as well as well
as what is recommended in case like this.

Thanks,
Marc
