It lost signal when held that way. It didn't drop calls. As explained in the anandtech article, they couldn't get it to drop a call once.

Curious: What happens when, during a call, you lose signal and don't recover it? If the call doesn't drop, does it just stay connected, waiting for the signal to come back?

I think the point is that it wasn't ever a complete loss of signal. Signal strength drops a little, maybe the baseband turns up its gain and burns a little more power, and the call stays connected.
