Alamy seem to have reverted. For a while I wasn't seeing too much of the old 'office party' search hit which was the head office of a political party, but recently I've had similar mismatches, of which I offer two as examples:
'George Ferguson' - returned the Adam Ferguson Building (Ess) in George Square (Main) Edinburgh.
'George MacDonald' - returned Lesley MacDonald (Ess) in George Square (Comp), Glasgow.
How much the caption is influencing the search results, I couldn't say.
