Venini does have things that were designed in one year, then made or reproduced in later years. I remember one time seeing a fish signed Fulvio Bianconi that was made a year after he died according to the dates. I wrote the Bianconi family to ask about it, and yes, it was a Bianconi design. It really isn't unusual if one thinks about it. The glass is not signed by the person themselves, but by someone else simply stating who did the design. (I wonder if they might reproduce the designs a year after the person dies as a tribute since the Bianconi fish and this bowl were made a year after the deaths. I've never heard this one way or another, but it would be a wonderful tribute, especially if some of the money goes to the estates or charity.)
