Feature; it's documented somewhere in the Exim manual, although I
remember that it was a bit indirect.
This happens with more than :include:/some/file. Exim re-routes and
re-expands top level addresses every time a message is retried (except
top level addresses that are marked as already being fully delivered)
and just throws away final addresses that it's already delivered to.
Anything with a variable expansion can change (.forwards, alias files,
etc) and in fact you can utterly re-route a message by changing the
Exim config file between retries.
