Firstly, the more you sit back, the more you have to angle the torso forward to compensate, so yes, lower back forces will increase dramatically, if you keep the shins vertical.
Secondly, I don’t know why you would ‘sit back’ into a box squat, since you must then ‘rock forwards’ to initiate the concentric portion of the exercise. This is a faulty movement pattern IMO. Use the box as a safety stop and/or to eliminate the stretch shorten cycle, NOT as a seat to plop onto.
Keeping the shins vertical is a bad idea IMo since it is not a natural squatting position really, risks the lower back and can lead to synergisting dominance of the QLs, resulting sometimes in facet irritation and LBP.
I don’t think there is as much danger to knees during the regular squat as some of you think. Allowing the knees to come slightly past the toes is a valid coaching cue and sets the body up for triple extension nicely, unlike the ‘shins vertical’ squat which has more problems than benefits IMO.
