Default Hand Propping

I was watching The Great Waldo Pepper for the zillionth time and noticed something about how they hand propped.

Rather than pulling through an intake and compression cycle clockwise (pilot's view), they pulled it counter clockwise. When the crank was at or near TDC of the exhaust stroke, the prop was released, and the compressed air kicked the engine through a firing/ignition cycle. Is this the norm? Or is it only done on some engines?
