By that logic, DC style widowmakers are counterproductive.
I hope you win this argument, so that I can stop doing them. lol
I have a love/hate relationship with those.
Lol, well, I’m certainly all ears if anyone wants to elaborate on this. Admittedly I’m not the most well versed on DC Training protocols.

I’ll give the topic a shot.
First, you can never truly “deload” the upper leg musculature during an exercise like squats (unless you’re talking about racking the weight between reps). Even if you were to lock out the knees so that the bone structure was supporting the weight, the upper leg musculature would still need to contract to stabilize the knee/hip joint.
Yes, standing (with knees and hips still slightly flexed) places the muscles in a more advantageous position (due to leverage and myofibrillar cross bridge contact) than they would be in at say parallel, or atg. But the leg musculature is still having to support the weight of the bar.
Otherwise, why ever do anything other than weak ROM partials?
Second, the quad “widowmaker” protocol that DC training (and is basically the “breathing squat” protocol popularized by Strossen, and seen in the video above with Arnold) is designed to place the upper leg musculature under a load for an extended duration of time. The theory is that since the legs (quads especially) are used to supporting and carrying around the bodyweight on a daily basis, they respond well to longer duration exercises.
Standing and taking a few deep breaths between later reps allows for some energy replenishment, but since the muscles must still support the weight and therefore must stay at least partially contracted, they aren’t allowed to fully recover. One is therefore able to “gut out” quite a few more reps with the weight than they could if they had simply gone to technical failure without the rest, and there is also a very pronounced “lactic acid” release (which some argue is correlated to GH release).
Not saying that this is the only method of training legs that works, or even that it’s necessarily better than other methods of leg training which don’t see to prolong TUT. Just trying to explain (to the best of my understanding) why it’s done. I do think it’s a very effective method though, personally, especially for quads. Platz would probably be the best example, but there are quite a few other DC’ers out there who swear by it and have the wheels to back it up.
Here’s Justin Harris showing how it’s done:
And of course, Platz:
I don’t really think that such extreme methods are necessary for most upper body exercises though. If you want to take a breath between your last couple reps (and try to get one more), that’s probably as far as you need to go in most cases.
