Is it normal that when I play at a slow tempo, my pick is going back and forth normally, but when I speed up I sort of turn it clockwise a bit almost like I'm playing pinch harmonics?

This is frustrating when a part is in a certain tempo where I can't choose which technique to use for it. And as I practiced getting faster with the slow technique and slower with the fast technique, it sometimes messes up how I play riffs that I already knew.
