I had the same confusion from a Star trek next episode. Gordie & Roe 'phase out' and save teh ship from a [phased] Romulan..I think my favorite line from any show ever comes from when Jack is on the set of "Wormhole Xtreme!" and the girl character is asking the producers "So I can walk through walls?" and they say to her "Yes, because you're OUT OF PHASE".
So she pauses and asks them 'So why don't I fall through the floor?"
And they look at each other... "Ahhhh, we'll get back to you on that."
