It's not different because it happened at first. His statement could just as easily have been if the Runner is obstructed rounding 2B but in the OP the runner was at 1st.

Because it would encourage the first baseman to take out the runner while the 2nd basemen took the throw for the tag. A good tackle before first base could leave the runner off the base easily long enough for the ball to come in and get the out.
(Even if you dealt with it with an ejection at the right time in the game it might be worth it.)
