2012 U.S. novice champion Karen Chen - Triple Lutz-double loop 

The salchow doesn’t have a lift assist as much as the loop does. Think of the salchow being like an axel since the jump doesn’t have a assisting thrust something like one jump that gives a toe pick of an assisting foot? A pre rotation is normally associated with a salchow and not as much with a loop, but was the execution of the loop a delay before making something like a forced rotation?
