https://www.w3.org/Consortium/Process/Drafts/#TAG-appointments has this sentence:

The Team's choice of appointee(s) is subject to ratification by secret ballot by both the AB and the TAG, each requiring a two-thirds approval.

There was some confusions as to what "each" means, the two possible alternative being:

• each appointee must reach 2/3 approval (of the TAG+AB counted as one body)
• the TAG and AB must each separately reach a 2/3 approval threshold for the appointment to be ratified.

Based on the issue and commit that introduced this (#715 and bcc0877), I think it is clear that the second meaning is intended.

We should clarify that to avoid confusion.
