In have wrote a workaround for the problem i posted that goes into this direction. I just check whether the url has changed and remove the submodule by hand if it did. See https://github.com/kollerma/git-submodule-tools if you're interested (its in git-fix-submodules).

What is the purpose of having two different submodules in the same path? Identifying the submodule by url however would probably make things considerably faster. At least in my case, since I have checked out different branches of the same repo at different paths as submodules.
