I am sure there is a reason - probably with how best to care for the grass pitch particularly with artificial "sun" lighting - but I think the expectations will be a number of non-NFL events at the stadium also - concerts and such, where they will want the grass pitch out of harm's way. And, they hope that the NFL grows to 10+ games per year if a team relocates to London.
I think it's more to do with the height of the pitch. For NFL games they want it lower so that you are able to see over the players and your sightline isn't blocked. I'm not sure how you would make that the retractable portion if it is to sit lower than the Spurs pitch.
