It appears that Vino didn't sprint against Danielson for the win. From a Velonews report of the press conference with Danielson:

Press conference: What happened when Vinokourov came up?

TD: He was chasing me but he really wasn't gaining much ground and my director thought it would be better if I waited and we worked together. Obviously he's a great champion and he didn't sprint me for the win. Although I pulled a lot and he pulled a lot. We didn't exactly talked about the situation and he's a great champion.
