The description of the illusionist's bracers states (GGR, p. 178; emphasis mine):
A powerful illusionist of House Dimir originally developed these bracers, which enabled her to create multiple minor illusions at once. The bracers' power, though, extends far beyond illusions.
While wearing the bracers, whenever you cast a cantrip, you can use a bonus action on the same turn to cast that cantrip a second time.
However, it seems to me that the effect detailed in the second paragraph would not actually allow one to cast multiple minor illusions at once as the flavor text in the first paragraph says, because the description of the spell minor illusion states:
The illusion also ends if you dismiss it as an action or cast this spell again.
Am I missing something about the illusionist's bracers that allows you to cast two minor illusions? Or does this magic item not actually allow one to do what its flavour text suggests?
