@backnforth I've seen this approach work. The bottom line is still poundage progression in medium to high rep ranges with good and consistent form. If any method allows for that, it's good.
I generally prefer taking sets all the way (or close), and that's usually how I program training for clients and it's a very popular approach because you're getting the most out of every set and you're accumulating a lot of effective reps. I personally think that all makes sense however I've seen other approaches work, ones like what you're describing here because they just rack up a lot of work with heavy weight.
Call it tonnage or whatever, that term has fallen out of vogue recently but whatever you call it. This is the accumulation of a lot of reps with a challenging weight. Sure the first couple of sets are easier, but as long as you're doing enough of them you're going to get a reasonably good growth stimulus. A lot of Powerlifters train this way and grow just fine by racking up a lot of sets at a given weight with none (or few) of those sets reaching failure. We forget if we step out of our bodybuilding world for a second, a lot of what we know to be true is due to the current echo chamber.
There is also an argument to be made for alternating periods of higher intensity and lower volume, with higher volumes across the year for the best long term growth and longevity.
Typically speaking you'll need more of these sets to equal the stimulus of less sets taken all the way. From what I've seen the need to maximise set intensity or set volume really comes into play when a lifter is a little further along. At that point you just need more stimulus, whether that's from really maximising set intensity or upping the volume a little.
It's not how I would do things, but if you like this approach and you're making progress then crack on.
