The question came up yesterday when we had my fan card, Meadow, on a board with Castles. Meadow is a VP card costing $6 that reads "When you gain this, gain 2 differently named Victory cards costing less than this.". The question was whether you could gain 2 of the < $6 Castles. It is actually more restrictive than Stonemason, asking for differently named cards, but as the gains are sequential, i conclude it still works. Probably the confusion came up because "differently named" sounds like a comparison that needs "access" to both cards at once - if that makes sense. Is there an official card that tells you to gain several differently named cards? I can only think of Pilgrimage, but that seems rather different, as the cards you have are different, and you just gain copies of those.
