No Peter I wouldn't buy one before and I won't buy one now. With that said here's why I think the two photos are from the same play.
1) The photos as pointed out before were taken from two different angles. The bottom photo was further up the 3rd baseline than the top.
2) Lord's right hand, Lord's head, and Joe's right arm all have moved proportionally from one photo to the next. Joe's right leg, Lord's feet, and Joe's head have all maintained their position. Nothing is out of place from one photo to the next.
3) The angles surrounding the bag including the curvature on the home plate side are identical.
I know this isn't proper photo identification, but it's pretty compelling to me.
