Yes, Paphs and Phrags are tropical lady slippers, the Asian species growing in some of the same regions as Neps. Sounds like Jag has one of these tropical types which makes caring for it a lot easier. Be sure the pot has drainage holes and pot the plant with fine diameter bark and you won't have to worry about overwatering.
You can grow the tropicals outside in good weather, mine bloomed well after spending the summers on the patio. Just don't leave them outside once temps get down to 50*F or so since they don't die back to a corm and come back every year like a Cypripedium does or is supposed to.
