Obstruction result of throw

[umpire_scott]

R2 is stealing third.  The throw from F2 pulls F5 off the bag and into the path of R2.  As a result when R2 slides he comes up short of the bag.  F5 is essentially laying on top of him at that point and applies the tag.  The obstruction rule seems to clear the fielder of obstruction as long as he is making a play on the thrown ball.  Is this always the case or are there any interps where if he is laying on him, but still in possession of the ball, he can be construed to have not given him a "path to the base"?
