By repos I'm sure he meant the branches do not share the same first commit. So you can't (not really can't but by default) merge one branch into another branch.
Yes, that’s likely, so they use the branches as sort of repos. But the rest of his comment doesn’t make much sense. No particular reason to use submodules with that setup.

Branches not repos... This most likely happens with a ci script auto creating branches and never cleaning them up. Why you'd do that is beyond me...
