Yet another or did he take the one from pbuilder?

This destroys the determinicity of build dependencies. So if I say

  Build-Depends: lib-new-name | lib-old-name

so the package builds (for users) in both stable/testing and unstable it
is no longer given which library is used by the unstable buildds. Some
will pick lib-new-name and some, where the new lib isn't compiled yet,
lib-old-name. And so on.

I always heard determinicity was a wanted feature for the buildds.
