Help me understand the following forks

In reply to RB87:

There is no difference between

 forever begin
  fork
   statement_1;
  join_none
  fork
   statement_2;
  join_none
end

and

 forever begin
  fork
   statement_1;
   statement_2;
  join_none
end

or

forever 
  fork
   statement_1;
   statement_2;
  join_none

Can only guess this was from cut&paste.

BTW, it makes no sense to have a function call, or any other non-time consuming statement as a fork’ed process.
