I think it is slightly amusing that he gets the Liverpool vs United wages thing wrong. However, the piece is clearly more about defending his idol Bielsa than anything else.
For a lot of football hipsters, of which Wilson clearly is one, Bielsa is like a prophet. A lone voice in a wilderness of direct, long ball football, preaching a message of tactical innovation and sophistication. Anything that takes the sheen off of him, like a 5-1 loss, must be explained away. Ole was, as you've pointed out, incidental to this story. This defence of Bielsa would've come regardless of who Leeds lost to.
