An undocumented mis-feature in git-difftool is that it allows you to specify a default difftool by setting GIT_MERGE_TOOL. This behavior was never documented and was included as an oversight back when git-difftool was maintained outside of git. git-mergetool never honored GIT_MERGE_TOOL so neither should git-difftool.
