[sv-bc] exported task declarations in modules

Section 20.6 has the following text:

"If the tasks or functions are defined in a module, using a hierarchical name, they must also be declared as extern in the interface, or as export in a modport."

First of all, the hierarchical name is really an interface identifier.

Secondly, is this implication bidirectional?  If tasks or functions are declared as extern in the interface, or as export in a modport, must they be defined using an interface identifier?

i.e. can this module be connected to the interface show below?

module slave (interface i);
  task read(...);
endmodule
interface ch;
  modport sl(export task read(...));
  modport mstr(import task read(...));
endinterface
