I've tested the revised macro in a MSR. It went the entire raid without a flaw.
To make sure it worked I intentionally swapped forms (using all 3) after one, two, or 3 power activations (depending on form). The only thing that I ran into was having to press the macro twice when the animation swap didn't process on the first click. I run into that issue frequently with all my form macros and key binds.
