I think you're right. After all, The melody of the verse repeats
between verses, so without the words repetition is no longer a good
indicator of the chorus, and a shift in style is as likely (maybe more
likely) to find the bridge than find a chorus.. By the way, some of
the papers referenced seem confused between refrains (which form part
of the verses) and choruses (which are separate musical units).
