The issue is that you are limited to movements which do not pass your center line, otherwise your swords will get in the way, not because of your swings, but because of your opponents actions, which will block or parry one of the strikes and halt it in a position that messes up your chances of delivering the second sword strike.
Strangely enough, I believe the KoH movie did it far better than GoT, simple and straight movements all while pushing towards the enemy;
