If you apply 1100 psi of pressure (a bit too much), the ABS might switch between 900 and 1100 psi at high frequency, generating 1000 psi on average.
Now imagine you're pushing 1500 psi instead.
ABS can alternate between 1500 and 500, and each time it goes in the 1200–1500 range the wear will be
much higher than in the previous case, or in case of optimal braking.
Kinda like drilling a hole in concrete with a regular drill vs impact drill.
So even though the amount of energy is the same, and thus temperatures should be (roughly? exactly?) the same,
it's possible that other things can significantly change the wear rate.
Hopefully this mental exercise isn't too far from what's happening.

Brake system is sensitive to the apply rate, temperature, pressure and speed (this is covered by AK Master).
One evidence for me of what is going on is to compare the heat checks on the brakes, where in one you can see much more pronunced cracks. Which for me, leads to thinking that may had heat spots, which happens in case of BTV or other issues.
