If he* did that, and found that one player had stats that were 'poor' compared to the others, he'd probably allow the player to reroll them stats, for balance's sake. And if the player rerolled and got better stats, time would be wasted when the player makes appropriate changes to his c-sheet.
Besides, when we meet up to roll stats (and have lunch/dinner/breakfast) and create characters (this always happens a few days before the game actually starts, for expediency's sake), we get to sit around and shoot the breeze for a couple hours, outside of game.
