A Git branch is nothing else than a "named pointer to a commit" (that's a fundamental different concept than in other well-known VCS).

This situation is clear, commit A is on branch-1, commit B on branch-2:

  o A [branch-1]
  |
o | B [branch-2]
| |

After merging is becomes unclear whether A (or B) originally was on branch-1 or branch-2:

o [branch-1] [branch-2]
|
o merged 
|\
| o A
| |
o | B
| |

Maybe you can guess on what Git branch the commit A was if you have tagged parent commits of A, e.g. release-1 and you know that this tag only was given for commits in branch-1.

o [branch-1] [branch-2]
|
o merged 
|\
| o A
| |
o | B
| |
| o
