Yes, but two points:
1. It can be done on a table, as Marlo & Ascanio did -- the point is that the pressure is on that inner left corner.
2. The pressure is best kept more to the left than on the inner edge. Think about the torn card: there's more missing from the length of the left side than there is from the inner side. The key to to have as little pressure on the torn card as possible. Looking at how I've been doing it, I tend to place my thumb (if holding the deck in my hand) or index finger (if on the table) on the corner and then roll it slightly to the left.

Not necessary -- I do a relatively soft, slow riffle. A wide riffle is good, though. It's done with my right middle finger, which moves in an arc upwards and towards my body. The middle finger is contacting the deck at the outer right corner, slightly more on the front of the deck than on the side. I also place my thumb on the back of the deck (lightly...I'm not really trying to put pressure on it here). Think of it as if you're trying to create a current of air out of the front of the deck (pretend you're finishing up Skinner's Mona Lisa Card Trick).
Another tip: bevel the deck a bit forward and to the right. This helps relieve some of the pressure on the card that I noted above when discussing the grasp on the inner corner.
That's all for now, though I feel like I'm forgetting something. Perhaps more later.
