This isn't the first confusion of this type with wireguard.  It too me a
while to figure out and understand the distinction myself.  This
suggests that the documentation could be improved or (maybe and?) that
the choice of configuration names might be suboptimal.

While we're still in the experimental stages is a good time to propose
improvements in naming.  Is there a better name to give either Endpoint
or AllowedIPs (or both)?
