Oops! You have discovered an infelicity. The splitting up of the pipe
command and the expansion of its arguments happens at transport time, not
at filter time. I agree that this isn't very clear in the documentation.
The value of $thisaddress has been lost by then.

I have added this to the list of bugs that need fixing. Thank you for
the report.
