How does a command find out who called it?

Completely depends on your code and the order in which the handler needs 
information.

Just as a (completely contrived) f'rinstance, what if the code looked 
like this:



local foo

on finishUp
   send "saveMe" to card id 1002
   delete variable foo
end finishUp

on saveMe
   put foo into URL "file:/tmp/saved.txt"
end saveMe



In that case, if you added the " in 0 milliseconds" you'd be out of 
luck, as the variable "foo" would be gone.  It wouldn't cause an error, 
as saveMe would assume "foo" to be the local variable defined at the top 
(or if it didn't exist it would be created (and empty)).
