Double negation in parameter description

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/9.6/static/sql-refreshmaterializedview.html
Description:

In the description of the CONCURRENTLY parameter (3rd line/paragraph, the
statement employs double negation which makes it hard to read and
understand.

"This option may not be used when the materialized view is not already
populated."

I guess the author would want to mean:

"This option may only be used on a populated materialized view."?

Your clarification is much appreciated.

I know this is six years old, but fixed in master with the attached
patch.
