Actually it's worse than that, it just concatenates requires: and any 
depends: lines, applying the current concatenated list to each version, 
as it seen (fixed as of 2.883)

These are lists, not sets, so can (and will, in this scenario) contain 
duplicates.

I don't know what could have given you that idea. It's not released yet.
