Of course.
There is nothing in Documentation/git-submodule.txt to inform that submodules
clones are different from regular clones.
I will write and propose a patch for the documentation.

I think I should give an example.
If I have a hierarchy like this :
superproject/submodule/subsubmodule
What I often do is:
superproject --> submodule --> subsubmodule
| ^
'-----------------'
Where '-->' is a gitlink.
That mean .gitmodules and index of the superproject contain both submodule and
submodule/subsubmodule.
And also mean (and that is the point) subsubmodule is a direct 'child' of both
superproject and submodule.
In this case where should the separate gitdir of subsubmodule be placed ?
- In superproject/modules/submodule/subsubmodule ?
- In superproject/submodule/modules/subsubmodule ?
- Depending on the 'git submodule update' command order ?
- Or both ?
