Is this batter's interference with F2

[DTQ_Blue]

R1 on 1B. The batter is bunting and is fairly tall. She offers at an outside pitch and misses, R1 is going. F2 pops up to throw and batter is still leaning over the plate from offering at the pitch. One foot is partially over the batters box line. Rather than stepping forward and throwing, F2 stands upright and short arms the throw because the batter is leaning over the plate. Amazingly, the throw to 2B gets the runner. There was no contact between F2 and batter, though if F2 stepped forward and threw the ball, there would have been.
