That's pure insinuation. Git documentation could be far from ideal, but
it has most of information there. Here is quote from Git manual page on
merge for you. It mentions what merge does to working tree 4 times, and
tells you exactly where it puts the two sources of conflicting merges:

[QUOTE=git help merge]

TRUE MERGE
       Except in a fast-forward merge (see above), the branches to be merged
       must be tied together by a merge commit that has both of them as its
       parents.

       A merged version reconciling the changes from all branches to be merged
       is committed, and your HEAD, index, and working tree are updated to it.
       It is possible to have modifications in the working tree as long as
       they do not overlap; the update will preserve them.

       When it is not obvious how to reconcile the changes, the following
       happens:

        1. The HEAD pointer stays the same.

        2. The MERGE_HEAD ref is set to point to the other branch head.

        3. Paths that merged cleanly are updated both in the index file and in
           your working tree.

        4. For conflicting paths, the index file records up to three versions:
           stage 1 stores the version from the common ancestor, stage 2 from
           HEAD, and stage 3 from MERGE_HEAD (you can inspect the stages with
           git ls-files -u). The working tree files contain the result of the
           "merge" program; i.e. 3-way merge results with familiar conflict
           markers <<< === >>>.

        5. No other changes are made. In particular, the local modifications
           you had before you started merge will stay the same and the index
           entries for them stay as they were, i.e. matching HEAD.

       If you tried a merge which resulted in complex conflicts and want to
       start over, you can recover with git merge --abort.

P.S. You sound like pure Git hater most of times. Haters will hate.
