Only problem with this kind of lifting is if you are really strong or have potential to be really strong at everything but one movement pattern. It makes it difficult to work on your weakness because you're only training 1-2 lifts per week when half or all of those lifts are occupied by a movement pattern you're, say, genetically weak in, your overall gains will suffer when focusing on that movement pattern.
For an example, say you had a massive back squat, hack, squat, jefferson squat, trap bar squat, any deadlift, any floor pull or squat but you had no chest strength to speak of, tiny wrists, long ass arms and very little genetic potential to build a big upper.
So this week you're doing your two movements, bw dips and not even 2plate bench. Well...you're not getting much out of this compared to your lower days when you're squatting and deadlifting 600+ lbs.
My point is this routine works better when your potential is welll rounded and you can build a strong upper and lower but not everyone can and thus you miss out a lot by spending so much time working a proportionately weak body part when another routine would have you doing much more work on those days.
I would agree otherwise focusing on one movement will bring it up fastest specificity rules but not everyone has potential to be well rounded and this training fails then.
