I guess that's why she only do a single 3T at US Nats, which leaves her only one combo to compare with Sasha's 3 3/2 combos, very vulnarable. But in a long run I think her coach is trying to help her get rid of the bad habbit(or musle memory) of falling back on 3t/2t when a 3t/3t is planned. Either you do a 3t/3t or just a single 3t, which again will leave her vulnarable place she difinetely dose not want to be in competetion, no more fall back on 3t/2t. But at US National she didn't need that 3t/3t after Sasha's fault.
