No, no.

We're talking about the second completion prompt, when you have picked 
an identifier to navigate to, but there are multiple matching locations 
to jump to.

Right now you see an *xref* buffer in such situation, but 
xref-show-definitions-completing-read uses completing-read (a second 
time) instead.
