If you two have the same commit that is a guarantee that you two
have identical trees. The reverse is not true as logic 101
would teach ;-).
Doing fast-forward instead of doing a "useless" merges helps
somewhat but not in cases like two people merging the same
branches the same way or two people applying the same patch on
top of the same commit. You need to compare tree object IDs for

Is it "you could assume" or "it is guaranteed"? If former, what
kind of corner cases could invalidate that assumption?
