Demotion question (Loz Vegas)

so the horse last night at Sandown which got disqualified and Loz Vegas which finished 2nd got promoted to 1st

If the Godolphin horse (Henry Lawson) had pipped Loz Vegas for 2nd, do you think the disqualification would have stood, and Corinth placed 3rd, Loz Vegas 2nd?

or do you think the disqualification would have only happened had Loz Vegas had the chance of being promoted from 2nd to 1st, instead of 3rd to 2nd?

Cant really argue about the DQ really, but think it might have made it more interesting if the win was off the boards for Loz Vegas?
