Yes.

It's one of those relics from the time when MS-DOS started out as a CP/M 
clone with a few added features. CP/M did have the concept of drives but 
didn't have directories, so one working directory per drive would give 
you the opportunity to have programs ported from CP/M stick to drives 
only, and yet prevent them from spamming the main directories of each 
drive they'd work on.

So back then it was probably a good idea.
