They twisted the cables on a binary cam to correct the lean?

Maybe because I've never done it to fix lean or maybe because I'm tired from a busy day, but I can't wrap my head around that.

I've done it to correct timing.

I've done it to correct lean on single cams and cam and a half's, but a binary cam?

I've worked on Elite and Bowtech... Huh? If you can explain it to me, please do.
