Well, yes it's a more than a little pedantic, but I think your statement may be too strong.
For example, at least one member of the Nobel family has objected to using their name on the prize:
> Nobel accuses the awarding institution of misusing his family's name, and states that no member of the Nobel family has ever had the intention of establishing a prize in economics. [from Wikipedia]
Also, while it's true that they're administered similarly, it also is true that they are funded from different sources. The Economics prize is funded by the (100% state-owned) central bank of a monarchy. Does that matter? Maybe not, but it's certainly a bit smelly and some of their picks in the past don't seem entirely justifiable solely on academic merit.
