Hi Akimbo,
I've looked at the replays multiple times and in my opinion I believe that the user IS macroing.
Here's why, in the second replay it's apparent that he hasn't started relying on it completely you can see he stills still dashing and moving around, he also still has massive control and does that delayed massive. However, in the third replay you can see he instantly massives while stuck in the corner which no glad player would do. He also does that awkward little stop before going into the corner which I think is him toggling it. In the fourth replay there are immediately two instant massives and he starts off the round by dashing normally and then quickly switches back to jumping in place tbfing with the enemy team away from him, which is another toggle. The fifth and sixth replays also show lots of awkward pauses immediately followed by jumping in place and tbfing. Aswell as a couple uncontrolled massives.
However, I'd like to wait for some more opinions on this from the others.
