Rollout of Trice position

In Response To: Whoops...I misread Trice! (Timothy Chow)

I rolled out Trice's position (for money with White owning the cube) and was surprised to find that 5/4 5/2 comes out on top, in contrast to my original position where 6/3* 4/3 came out on top and in contrast to Trice's verdict of 4/3*/off, which presumably was what Snowie told him. Evidently there's more to this position than meets the eye; I still don't really understand all the subtleties.
