[Iris-Club] A question on the completeness condition of COFE

Dear Iris Club,

The appendix (http://plv.mpi-sws.org/iris/appendix-2.0.pdf) says a COFE
should be copmlete:
∀n, c. lim(c) =n c(n + 1) (cofe-compl)

I wonder if why it is defined as above; more concretely, why not:
∀n, c. lim(c) =n c(n) (cofe-compl)

Note that the above conditions are derivable from each other by (1) the
condition of a chain that c(n) =n c(n+1); and (2) and (=n) is an
equivalence relation.

Thank you,
