A lot of people call that the "yellow DFA fake out". On dueling servers you will see it more often because some people use it as a tactic during their fights.
There is also a move that sort of looks like they are completing a yellow DFA but immediately do a backflip, etc. upon landing, without the normal delay that you see in a real yellow DFA. This move only has the damage of a normal swing in yellow instead of the regular yellow DFA.
