If it's like the OMS SMB, which it appears to be, you get the best of both worlds. It fills from underneath using your 2nd stage, but the air gets sealed in by a one way valve and won't deflate without pulling the dump.
You'll actually get a laugh about thinking it was orally filled when it arrives. They're a lot bigger up close.
