No, that's not the argument at all. Snowden's father said that he anticipated his son would return if he had a guarantee of freedom before trial, no gag order, and a choice of venue. This was widely reported and I am assessing his statements at face value.

Nobody but you has mentioned solitary confinement or Virginia courts; you're entitled to an opinion that that's the risk he's facing, but that has nothing to do with the statement made by Snowden's father. You don't speak for him.
