No it doesn't mean that unfortunately. This is how it reads:
(a) Where a ballot on an industrial matter has taken place, then any proposed change will only be agreed, in principle, by the unanimous decision of the full committee.
(b) Any such proposals should also be referred to a Branch Meeting and subject to ratification by the membership
(c) Where unanimous agreement is not reached, then the matter must be referred back to an emergency meeting of the full Branch, for acceptance prior to ratification by the membership. As best practise the committee will ensure that there is a communicator responsible for reporting back to all reps and membership during negotiations. The communicator will not take part in negotiations.
They've already voted to strike, so a change requires a meeting in any event.
It's a bummer.
