Well, it goes ahead with what it knows in that case.  I don't know.  I
guess it gets its information mostly from RPM.  Do the headers contain
any dependency information?

I thought about this too, but was trying to come up with a better
reason :).  You are probably right, the real reason is because it is
programmed to update headers on every transaction.  I guess it saves
it from doing it the next time it is run.
Anyway, to avoid this, you can run yum with the "-C" (uppercase)
option to avoid downloading headers unless needed.  So run "yum -C
remove <package>" if you would prefer yum not to check the
repositories.
