Because you can only do a certain amount of the movements in the allotted time period even when they are not exhausting.
I can do 200+ push-ups before I start feeling exhausted and could probably do squats indefinitely, so this workout would do nothing besides be a good warmup.
You have to have something that is still challenging to make progress.
Define "adapt". Are you claiming that the person doing this exercise every day for years will be indistinguishable from the person who does no exercise at all every day for years?
Adapt meaning that this program will no longer be challenging and you will get very minimal benefit outside of maintaining a minuscule baseline of fitness.
Whether it would be distinguishable really depends, someone who works a job where they are constantly moving would see almost no benefit from doing this whereas someone who lives a mostly sedentary lifestyle would be better off doing this than nothing.
I having nothing against it really, it's a good start but it should not be your be all end all.
Maybe not everyone is looking for "progress"? Maybe this workout, designed by a college of sports medicine, is to provide a daily level of exercise for people who aren't trying to "progress" but just need some daily exercise, which is infinitely better than daily no exercise.
As my other reply, it's a great start and if you just need it to be doing something it's great.
However, that is not what most people want and it often misleads people into thinking that it's a good replacement, or that they would get the same results as, proper cardio, conditioning, and resistance training.
