You are correct. In fact, you can get really strong training once a week. Fact is, this guy's training methods are basically kind of appoaching an optimization for bulking (building the most muscle mass possible) combined with laziness (only training once a week).

The big criticisms of this kind of training would be:

1.) athleticism (he recommends machines, but free weights and calisthenics--replacing lat pulls with pull ups, muscle ups, etc is much better for athleticism)

2.) strength (he recommends machines, no momentum in movements, long recovery periods... this is basically how bodybuilders train to build the most muscle, but power lifters and athletes will optimize for maximum power, which includes momentum in their movements, and more endurance in their muscles)

3.) cardio/weight loss (you will burn more calories and build better cardio with higher volume, repitions)

4.) Injury (machines, low reps, high weights, all increase risk of injury)
