When it comes to double mobes I think the double just refers to the number of inverts, assuming a 3 was done -> and if more spins than that you specify by adding the rotation degree afterwards. So a double tantrum with a backside 3 would be a double moby dick. Maxim could've called his trick a double KGB (or named it a CIA lol).
Parks called his hit a switch double mobe. If he had done an extra 360 in there it would be called a switch double mobe 720
