I've read about this as the variegata change is a known trait. And I've read on one forum about the same "albino" change on a seedling.

As it has no chlorophyl activity, it depends entirely on the rest of the plant for sugars. You can call it improperly parasitic but it's the same plant, so it's not. It has only a branch very impaired. As long as the plant can furnish enough sugars to support the branch, it's fine. But at one point, the balance may be broken and if so, the vanilla will "make some choices." (It's not conscious so I'm being anthropomorphic)

You can wait until it hypothetically move back to a chlorophyl ON state, or cut the offender to help the rest move on. I'd cut, it "feeds on" the rest and drags it behind with a "dead weight", and you can't tell when or if it'll reverse to some variegated state or normal.
