Heh, there we go. The angle of the video makes it impossible to say for sure, but I think so. Does this make it excessive? Not by any inherently meaningful standard, because there really is none. Talking about this is like talking about politics, where if you're pissing a lot of people on both sides off, you're probably onto something. In the strength world, a 900 lb strongman deadlift done with straps, hitching, and a super whippy bendy bar might be a reasonable (not a perfect) analogy. Sensible people would say: that's an absolutely incredible feat of strength, while also acknowledging that's it's not the same as what we'd call a "deadlift" in competition - done without any straps or hitching and on a 29mm stiff bar. But then you get the people on one side who just say "straps, DL bar, hitching - that's stupid/cheating" and the people on the other who say "what the hell is wrong with you, that's 900 lbs, how much can YOU lift?" They're both wrong. It's an impressive feat of strength, but it's not the same lift as a conventional deadlift as performed in the non-recreational PL federations. An 800 lb squat done to 1 inch above parallel is impressive as hell and is still an incredible display of strength, but it's not the same as squatting 800 an inch below parallel.
The intellectually consistent position is that something can be an incredible feat of strength without being the same thing as, or meeting the standard of, X. And it's not being unnecessarily pedantic, either, if we're going to use words like "deadlift" to have a commonly accepted meaning.
Pressing 315 with a ton of layback is not as impressive as pressing 315 without a lot of layback, which in turn, is not as impressive as doing an absolutely strict military press with 315. But it's still impressive as all hell. Just like pulling 900 with straps and hitching on a whippy 27mm bar is impressive as hell, even though it's not the same thing as gripping a 29mm bar with your hands and pulling the same 900 without hitching.
And as I've been trying to convey throughout this entire thread, what constitutes "excessive" layback is really in the eyes of the lifter and beholder. For competitive purposes, I like the armpit/ass standard, but that's only because I personally think the inclusion of the press in meets makes the most sense as primarily an upper body strength test/display, in contrast to the squat and DL, and having that standard keeps it so a reasonable extent without requiring absolutely strict presses, which if judged strictly, would probably red light almost every attempt and just as likely make participation in this sport very low. But "reasonable extent" is itself subjective, and that standard is simply one of convenience, not inherent meaning. Additionally, that's only my personal opinion about the press in competition, which isn't agreed upon by everyone. Finally, even given that primary purpose for competing in the press, trying to limit the layback at meets comes with a large set of logistical issues to solve, as noted earlier. While tweaking can be done again in the future, the removal of any attempt to limit and judge layback in press competition probably makes the most sense.
