They took advantage of the ability to move two parallel faces at once making solution in 14 steps (if you consider Up and Down move at the same time to be only one step).
If they have a double-turn move they ALWAYS turned clockwise.
I think it's not important but probably an artifact of a standard notation, where we denote R as a clockwise Right face turn, and R' as anti-clockwise. The 180 turn can be done both ways, but we usually denote it as R2 instead of R2' (even if for human it will be more ergonomic to do a anti-clockwise turn) so the double-turns interpreted literally are double clockwise turns.
This is the visualisation of the scramble and the solution they used:
