They weren't his solution, no. They were the solution settled on by TfL which he initially tried to oppose. He was eventually convinced of it, but he had already been so adamant about Routemasters (the famous 'ghastly, dehumanised' quote) that he couldn't communicate why he changed his policy. Johnson reheated the policy partly because he thought there would be mileage in attacking Livingstone over this.
Aah - I see, Bendy busses were his (tfls?) solution to the original Routemaster. I misread your comment that he (and then Boris) wanted a solution to replace the Bendies.
