The article doesn't say when the visual and audible alerts happened, they could have been minutes previous on another stretch of road. I agree he should have disabled Autopilot there if he knew it was an issue, however why didn't Tesla recommend that to him when he made the report? And the removal of the concrete barrier may have been a new factor that he didn't expect and caused Autopilot to fail much more severely.
