Query on Link In / Link Out Nodes

Hi ,

I have a query on Link in / Link Out Nodes.
Documentation says : " Note: Links cannot be created going into, or out of, a subflow."

Does it mean - that

  1. we cannot have Link in / Link Out within a subflow ?
  • Or
  1. we cannot have one end point within a subflow and the other end point outside subflow.

  2. Will the below be valid ? It works. But want to be sure i understand it right.

  1. You can’t have one end in and one end out.

Thanks @dceejay .
(Background - i want to start using Dynamic call feature of v3 - so want to sure before i get to Design).
Thanks.
