I don't think the stewards screwed up, it depends on what you feel the jockey of the 1 was doing.

race replays Monday 2/25 race 1
the action occurs near 25 seconds on replay
the jockey started pulling up at about 23 seconds, then clipped heal of 5 at 25 seconds, then about fell off.
I saw the head-on replay which showed the 6 and 5 racing to the corner and the jockey of the 1 about fall-off, but could not really tell if there was a lane left or not. When viewing the other 2 angles supplied by Beulahs website, I can agree with stewards - and they might of even had more angles than the 3 I have seen.
