Yep, I rewatched his video, and an asymmetric stringing of the suspension (tight on the side your head/feet are on, loose on the other) plus maybe a Dutch ridgeline quilt hook, or maybe just a short loop of line ("triangle thingy") to change the tension angle will solve the diagonal lay problem.

They do not point out that the side loops only match a HH or TTTG hammock, nor do their suspension system instructions say anything about getting diagonal coverage.
