Ever have this happen?

was the membrane on?

[Steve R.]

The membrane was mostly gone when I took it out of the packaging. What little there was was between the bones, so I left it.

That was my thought too. The one time I had ribs twist but not as severely as this was when I having a tough time getting the silver skin off AND my grill got too hot. It was like the excess heat made the membrane contract. A quick slit between the ribs let them flatten out.

[Steve R.]

Except it didn't really twist, the shadows make it appear that way. The meat side is what contracted, with the silver skin on the outside as you look at it. I tried scoring the meat side, but no luck.
