Dewar benzene according to Wikipedia has the IUPAC name bicyclo[2.2.0]hexa-2,5-diene.

Is it correct to give this name because resonance takes place and if we fix a certain numbering, as resonance takes place, a different carbon would occupy that numbering in a cyclic manner? Similarly like saying benzene's IUPAC name is cyclohexa-1,3,5-triene would be wrong.

Kindly clarify.
