I will give you the benefit of the doubt and say that I am sure I don’t really have to explain, but anyway.You've lost me, here.
First vote, a free vote - tiny margin.
Revote almost instantly, Tories whipped - larger margin.
The first vote was an amendment to the original motion. It passed. It largely made the second vote on the amended motion irrelevant but they had to vote because that was the vote on the motion. Remember the first vote was just an amendment.
Voting against the motion when the amendment had passed was only a protest vote as it was obvious it was going to pass as it had already been voted on, even though they tried to whip at the last moment. Until this point the Tories has said it was a free vote. Realistically they had no chance of whipping successfully as they would have had to practically drag people across the lobby.
So the first vote was not a vote on the motion. The second vote was. So one vote. Not two.
