I loled. But genuinely curious. Is this tongue in cheek, or is it sound?

It's sound. Lining out things and initial and counter-initial makes it legal. Done that many times.

I can’t see any reason why that change wouldn’t be invalid if others are. (Though it’s probably good to bring it up explicitly so there are no surprises for anyone.)

[WalterBright]

That's why both parties have to initial such changes.
