No. He just made it look attractive.
He ended up getting hurt so many times it was laughable.
Mike Mentzer snorted crank and started ranting about logic, inverse ratios and Ayn Rand's "objectivism" to prove his point. He said there was only one "means to an end"
At the same time, there are also a million ways to New York from California, or "many ways to skin a cat"
There are many books available on the Scientific approach to bodybuilding sans the "dogma"-- that doesn't mean that HIT doesnt work, its just that its so fucking easy to get hurt and bored when you are ultimately doing one set to complete total disastrous fucking failure.
If you took a guy that had basically been doing your typical "Arnold" type reps, sets and weights and then through him into a HIT routine, the guy would be sore enough after to believe that it worked, but most guys who want to use "logic" with HIT, make their own concoction. They hybrid the workout to combine more work out sets along with more negative work, but never to where you totally fail on the negative portion of the rep, which, by the way, is dangerous as fuck without an intelligent spotter.
Failing on a positive rep is cool, that's where "cheating" steps in.
Failing on an isometric/static rep is cool, you just can't hold the weight anymore
Failing completely on the lowering portion of a rep is where you have completely toasted all reserves and made huge inroads into recovery. You can also drop the weight. You don't recover until your Central Nervous System has recovered.
There are ways to use HIT that can work for you, but not in the biblical translation. I believe working throughout each portion of the rep according to the strength curve is an intelligent move, but you have to have an intelligent spotter or some kind of variable resistance equipment like Kaiser makes.
Have fun. Give it a try. Make up your own mind.
