You guys are all missing the point! The fact that Mario's foot is partially entering the wall between two bricks clearly means they are demonstrating the SMB wall jump glitch. The lava proves it as he'd otherwise be dying, but a wall jump from that position would save him. The fireball is simply because the person playing the game was mashing buttons to get the wall jump correct and fired a fireball at the same time.
Hence, it is quite clear, given they demonstrated it on the box, that the wall jump is not a glitch, but a feature. It is and always has been intended to be a legitimate maneuver. We just thought it was glitchy all this time...

Joke post, of course.
