More to the point the numbers wouldn't work anyway, not enough Tory rebels that would vote for him even if there were few Labour rebels.

This is about trying to box in the Liberal Democrats. Labour know the Liberal Democrats have the strongest objection to Corbyn of the Remain parties and they are also the biggest threat to them outside of that. So it makes an offer for an alliance that won't work. If the Liberals accept it then it scares away Remain Conservatives in Lib Dem marginals 'Vote Liberal, Get Corbyn' and if they refuse then it damages them amongst Labour-inclinded Remainers too.

Labour can't stand the Liberal Democrats because they'll find it harder to move as left as they naturally would like if there is a viable alternative on the centre-left, they can't take the entire left for granted if they have somewhere else to go.

You give him way far too much credit. This was about Corbyn’s ego and not much else.
