It's actually that the blowby overheats the rings in the area of the gap.
Ricardo proved that back when rocks were a new idea. I found a reference to
it in his book "High speed internal combustion engines" years after I found
the cure.

Yes, the same technique will work with a dry block as I did on the TR-4
sleeves. And yes, you can use Comet or Ajax (or like stuff) with equal
results. You need to do a very very through job of cleaning if you lap into
a dry block 'cause the cleanser will not be friendly to bearings and smooth
surfaces.
I found that the chrome rings were almost impossible to seat if you did the
usual break-in at slow running and low revs. They would pass pressure and
oil forever. What I found that worked every time, operate the engine at low
speed for a bit, like three or four minutes, then take it out and run the
devil right out of it for a couple laps. The chrome rings seem to like this
abuse and they sealed up immediately. The slow running on the chrome seemed
to glaze the cylinder walls and never let a full seat occur. Yup, that's my
opinion.
