No, that’s not what “majority” means. A majority is 50% + 1. What you’re describing is a plurality.
If no candidate gets a majority of electoral votes – that would be 270 or more – then the election goes to the House. That’s the mechanism we’re talking about here. In the hypothetical you’re describing, 269-268-1, no candidate has a majority, and the election goes to the House. That’s more or less what happened in the 1800 and 1824 elections: more than two candidates got electoral votes, no candidate got a majority, and the House determined the outcome of the election.
What we’re talking about here is a little bit different, but it’s the same basic principle. Instead of the electoral vote being split across multiple candidates and preventing any candidate from getting a majority, what Jones is describing is the electoral vote being incomplete, of Trump preventing states from certifying their results, so that no candidate gets a majority.
