Yes, that's expected. The main technical reason is that a lot of the
subsequent submodule operations may read objects from the submodules,
and those could trigger on-demand fetches (if the submodules were
themselves partial clones) - but right now the fetch code is designed to
run only on one repository.

For those who would like to improve this state of affairs, one step in
the right direction would be to update the fetch and transport code to
support an arbitrary "struct repository" passed in, and not just operate
on the_repository.
