I think "implies the effect of C++11" is too strong wording. "related"
might be more appropriate.

See also comments here for connection with "volatiles":

Take note the Hans' correction that fences generally imply more than
volatile load/store, but since you are listing the related things in the
docs, I think the "native" Java example is good to have.
