I think in such a situation, for a defender to stand off, it basically indicates
1) he is delaying, allowing his teammates to fall back into position, especially if he is aware that being beaten would result in a clear path to a goalscoring chance or
2) the defender is very passive n inept, and doesnt have the confidence of getting the ball off his opponent.
From the video, i feel is the latter. From my years of playing as a defender, i would never allow it. If the opponent is extremely skillful, i would avoiding diving into a tackle but instead stay on my feet, put pressure by decreasing the proximity between the 2 players or at least repositioning myself in front of Pogba and force him back towards his own goal. Blind is a shit defender, useless one to one and perhaps he knows his limitations and that explains his passiveness.
