That's  a side  effect  of the  mechanism,  but the  way  it works  is
actually different. 

--three-way calls diff3 on the common ancestor, your version and mine.
It's not aware of the history  that lead your version and mine to this
point. 

Without --three-way, conflicts solved by --forward can come from

* Two  developers doing  the  same  change by  hand  (typically for  a
  trivial bugfix)

* Merging a patch which is actually a merge from you. 

The  usual   star-merge  can   distinguish  the  two   behaviors  with
--skip-present, but diff3 and therefore --three-way can not AFAIK.
