Wrong, it's a yum design flaw. 

E.g. if the mirrorlist file was on a local disc, yum would not try to
contact the mirrorlist on the server each time it is being invoked.

The work around from RH's side would be pretty easy: Ship a local copy
of the mirrorlist file as an rpm and let yum use this. Then update this
rpm at regular intervals.

Very oversimplified yes.

The difference is in "remove / install"
yum contacts the mirror server each time anew on each invocation,
apt-get doesn't

Try a dialon-demand dialup over a modem and you'll pretty soon notice
why I consider yum to be a "network connection hog"
