Maybe we have some different understandings of the “pushing foot” and “take-off foot”.
In my opion, in toe-assistant jumps, the assistant foot is definitely a pushing foot, but it is definitely not the take-off foot.

Just got it wrong about the "Front left" and "Front right", Lutz should be at Back left, Flip should be at Back right.

The comments posted here were intent to remind you, when you judge a toe-prick jump was executed correctly or not, you should not only focus on the edge of the supporting leg, you also had to determine whether the take-off is made from the supporting foot.
Use a SCREENSHOT to show the toe-pricking point, it determines what curve the edge could cut on the ice surface. For example, for Lutz, toe-pricking point should be located in front left of the entry curve, for Flip, it should be located in front right of the entry curve.
Use a GIF to capture the first take-off stage, i.e., from toe-pricking to the edge of the supporting foot leave the ice, during this period, the edge should continue to apply certain force on the ice surface and cut a certain curve, and the back part of the edge should come off the ice surface first.
PS, Flip used to be called “Toe Salchow”.
