Juli again:
What I can tell from all the conversations between Harry and Sluggy, 
he's always been a POTIONS teacher (he even taught Snape), therefore 
he IS a Potions Master. Snape knows both Potions and DADA, so he can 
teach either one, but imagine Minerva teaching Herbology or 
Divination, or Prof. Sprout teaching charms? It just doesn't work.
