Lots of that text could have been written by Pavel Tsatsouline. He's a big advocate of lots of short sets instead of a few long ones. His general rule is never more than 5 reps in a set of anything. This program, over and over, recommends taking sets of 3-5 reps with a weight that's 2-3 reps short of failure. That in a nutshell, is the Power To The People program.
For the general public, he recommends only 2 sets, but for the serious strength athlete, up to 20 sets are fine. The hypertrophy or not issue is settled by the rest period - short rests and a slightly lighter weight for size gains, long rests and a slightly heavier weight for strength. I have, e.g., done workouts where I'd do 10 sets of 5 with 5:00 rests using a weight that was my 7-rep max and it really helped increase my strength while providing minimal hypertrophy - after a few weeks of that protocol, I was able to make almost a 20% increase in my 1RM without doing any of the weights in between (ah, the wonder of kettlebells and their large weight increments.) The downside, of course, is that your workout takes quite a while this way - 1 hour and 20 minutes was a typical session for me on a single lift with the 10 set x 5 reps on long rest protocol. Since I work at home and could go to my desk between sets, that's just what I did so the time wasn't a total loss of income.
I recommend you follow the link to the 'Fast and Furious' article he refers to - also good stuff.
