Well, you usually can't infer much from what you saw after a crash. There are a number of possible reasons why it was there. Unfortunately, we also don't seem to get a lot of reporting on crashes after the first article any more, and that's usually very bare and based on the police press release. Before its coronavirus-related staff purge, the Standard usually sent a reporter to the scene who wrote a proper piece, and there were also often follow-up articles, but now they rarely do that any more, and neither do the local papers, mostly.
In the photograph in the Standard article, the lorry is pictured in the High Road at the junction with Broad Lane, its front wheels in the pedestrian crossing, with the picture taken from Broad Lane.

No information on whether it was a left hook or something else. The lorry could have been swinging out to take the turn, but it's not clear.
Best wishes to the rider.
