Thanks for the answers!
The part I was missing is that a backgrounded process:
echo bla &
is run in a subshell.
Somehow I managed to miss that information in the "Asynchronous Lists" chapter:
"If a command is terminated by the control operator <ampersand> ( '&' ), the
shell shall execute the command asynchronously in a >>>subshell<<<."
