I agree that the paragraph is unclear, but the requirement is nevertheless
important. Perhaps a better way to state it is that material sent to
a cache must already be in canonical form, eliminating the need for
canonicalization being done by the caching server.

This requirement also makes sense if things are to work with DNSSEC, BTW.
