It didn't look like it to me at all. From the man page:

   Examples:

   # match anything with a version containing 9999, which can be used in
   # package.mask to prevent emerge --autounmask from selecting live
   # ebuilds
   =*/*-*9999*

So if that works, one would assume that "=dev-qt/*-*5.6*" should work 
just as well :-/
