Even though the 'real' flip jump requires INSIDE CURVE ONLY after the turn, this kind of curves are created by some skaters like Mao Asada.

After the turn, the skater comes in with inside edge, turns to outside edge creating outside curve, and than turns to deep inside edge before jump.
ISU accepts this kind of jump as a flip because the skater eventually jumps with inside edge, but this actually is NOT the right flip jump.
look at Mao Asada's flip.

after turn, she changes to OUTSIDE edge, and THAN changes to inside edge before the jump. This creates bent curve, which is not supposed to happen during flip.
Mao's kind of jump is performed when flutz jumpers try to fix their flutz and the body remembers the movement when the skater is trying to fix his/her jumps.
So, Mao is not really doing the RIGHT jump, it's just the ISU and judges are ACCEPTING her jump as a flip because she is jumping with her inside edge anyways.
