Comment:
https://github.com/void-linux/xbps/issues/318 is the best thread for documentation of issues that I can find, although it is less relevant to this example. you can ping duncaen in the #xbps freenode channel if you want some more info. Sorry I do not have a better answer, just that virtual packages were sort of hacked together and break a lot of assumptions.
