I can't help but think that's wishful thinking rules lawyering. By their interpretation if you chose to stay in Swoop mode you'd have to move at least 12", etc, when they can't move because they Deep Struck... and Deep Striking is the defining aspect of their movement, here. That they came in by Deep Strike pre-selects their type of movement and uses all their ability to move. IIRC, there are other things that happen "at the start of the turn" and "at the start of the movement phase" that happen simultaneously, so the instant your turn has started you are resolving the things--like rolling for Reserves--that happen at the start of the movement phase. You are always in one of your 4 phases, there not being a "pre-phase" limbo to do stuff in.
What sphinx of plascrete and adamantium bashed open their skulls and ate up their brains and imagination? Imperator! Imperator!
