@i hate crackheads well you could say that, but Dragon Ballz had this insane sequence where Goku was shift jumping right to left feet and vice versa, while going super Saiyan, which signifies he has a mastry on his power and can go super Saiyan whenever however he wanted like it is his a piece of cake for him.
So it actually shows us that shift jumping is signifying that the character has a total mastery on his power.
