github - What does SmartGit saveAfter saveBefore mean?

Question

There is a branch in stage A that mistakenly overwrites the file file.php, and then stage -> commit -> push has been updated to the remote (forming B).
View this file in stage A in smartGit, how to restore it to this stage, clicked Revert Rebase HEAD Rebase to HEAD but it is still useless.

The second attempt is to right-click on the file file.php in stage A. There is Save After Save Before What is the difference between the two?
