In the case of a stable release, x is %rel - 1, y is there to allow 
differentiation between multiple rebuilds based on the original %rel cooker 
package.

Note that this is done because cooker doesn't use distribution-specific 
release tags. Once cooker does (hopefully in a few months), this will be 
unnecessary, and release tags on stable using %mkrel will not be as ugly, but 
instead something like 1mdv2008 in cooker, 1mdv2007 rebuilt on 2007, 
1mdv2007.1 next package for 2007 based on 1mdv2007 (or similar).

You can control y by defining %subrel in your spec file before calling %mkrel:
%define subrel 2
%mkrel %rel

http://qa.mandriva.com/twiki/bin/view/Main/DistroSpecificReleaseTag has more 
background
