Yep, which is pretty much what I do on platforms too. Other than kicking my foot out to unclip, I don't find the process one bit different than how I ride platforms, including getting the bike to lean to the right.

As one who has started trialing SPDs very recently, I wish this was the talking point that was used more than the efficiency one. I'm not personally seeing much efficiency gain (and still not buying "pulling up" adding anything to my stroke), but the sure footed feeling is quite nice, and at times may encourage a bit more spirited pedaling.
