I think the problem that a lot of people who cannot swim well venture into scuba diving without much of the surface swimming skills. If your friend would be a good swimmer, then the friend would already be conditioned into breathing only through a mouth upon entering water.
Since your friend does not have that reflex, I'd say that your friend is a bad swimmer. No swimmer that can swim somewhat fast will breath through a nose.
My advice would be for your friend to take swimming lessons. Seriously.
PS: What is up with scuba students not knowing how to swim?
Being a swimming instructor for 17 years, this phenomenon is not new to me and it is extremely frustrating... I've had a couple of students - one troublesome child in particular - that somehow got open water certified, yet couldn't even swim front crawl without a snorkel because no one ever taught them how to pick their head up to breathe, or more importantly rotary breathe... This one kid would actually choke on water every time he started to swim face down, because he was trying to breathe with his face IN the water as if he had a snorkel. I eventually went to his parents, told them he needed to be in a lower level swim class (this was level 5 red cross) and learn the basics of swimming... The mother's argument was that he could scuba dive and snorkel, to which I replied, "you can't use an air tank in competitive swimming" which is where he was hoping to go once he got to high school. I saw that kid once more in a lower level class with another instructor, and she was equally frustrated with his insistence of trying to breathe underwater. Sadly, he never returned for another class after that... I hope his lack of swimming ability doesn't get him killed one day in his scuba kit.
