The game in the photo that identifies Jackson was from May 5, 1911. The teams played 4 games around then, 4 at the end of June (into July 1) and 4 in September. Unless it came from the last four game set, the photo was taken before half-way through Joe's first season. Now if they waited until year end to go through all sorts of photos, then I see your point. But if they already had decided on Lord and that photo earlier, I can see where the captioner would not necessarily have had reason to go back and check on the identity of the baserunner.

EDITED TO CHANGE: the September series was only three games, not four
