Git should generally do that automatically, unless both sides are
changing mydirectory. In which case it will produce conflicts.
Are you sure you really want to just throw out what the other side did
in mydirectory?

If git was able to auto-merge some files, then they will not be marked
as conflicts in the index. And "git checkout --ours" is about looking in
the index for conflicted entries, and then selecting one side.
I think what you want instead is to do is (assuming you really want to
throw out their side):
1. Start a merge between them and us:
git merge --no-commit remoterepo/master
2. Throw out whatever the merge came up with and make it look like
their tree:
git checkout remoterepo/master -- top
3. Now overwrite their version of mydirectory with what was in your
branch:
git checkout HEAD -- top/middle/mydirectory
4. Commit the resulting tree:
git commit
