It's pretty much the same. He's worked with strongmen and powerlifters (and other athletes), and used them in his process of learning about the spine. He discusses in his one of his books, and i'm sure he has mentioned things like this in interviews/articles/podcasts, i'll dig around and see if i can find any.
Actually generally accepted lifting technique supports his view on the role of the lumbar spine and the "core" - to transmit force. Other things like, lift with the hips not legs, "brace"/valsalva, not draw in. He's a huge proponent of "stiffness" (or, "super stiffness"), he has written a lot about this.
Also, I love when someone argues on the point of "spreading the floor apart" when you squat. On one hand, you have louie simmons (among others) tell you to do this - difficult to argue with him. On the other hand, you have Professor Stuart McGill tell you the exact same thing. Two completely different perspectives, one is to lift as much weight as possible, the other is to protect the spine by maximising the role of the hips and increase stiffness.
Also, he's one of the originals to debunk the alleged "safety" benefits of weight belts. It may be as entertaining as reading a dictionary but on this site (backfitpro) there's a weight belt article, also one on super stiffness, which is really all about getting tight, bracing, "co-contraction", which is also pretty much the same as Pavels "irradiation" concept discussed on here recently.
It's actually amazing how people from different back grounds with different goals (health vs performance, for example) often come to the same conclusions.
In terms of heavy lifting and health, as he says in that video, for optimal "health", you need just the right amount of activity, not too excessive, not too little. So, if optimal health is the main goal*, powerlifting probably isn't the best route
*but where's the fun in that?
