A beginner would be far better off with a simpler A/B setup until they have built a good base of muscle.
It's only a 30 set workout (providing you're using 3 sets per exercise), and there's also the adaptation phase that has to be considered too. The intensity should be moderate because the frequency of the muscles being worked is moderate. It looks like more then it actually is, when I first started out I did an Upper/Lower similar to this, and I didn't feel overtrained at all. The weights just went up.
