Those &s, ?s and = are just characters in the URL to the document which 
provides a list of mirrors. Apparently, it's a script, and release, arch 
and repo are the parameters to that script. This has nothing to do with 
yum directly, it's just centos webmasters implemented it in that way. I 
mean, the URL could possibly be something like 
http://mirrorlist.centos.org/$releasever/$arch/os or anything else.
