Convenience, possibly.  The bug hasn't gone away.

If the main package has Depends: %N-shlibs (= %v-%r), if a user has the
main and -shlibs installed they can't update to a new version-revision
in one step.  The build will be performed, but fink won't install the
update:  the new -shlibs has to go in first, and the old main package
will complain because of the %v-%r mismatch.  But afterwards apt-get is
perfectly happy to figure out how to do the upgrade.

I'd argue that (= %v-%r) is a safer option.
