Have you looked at the interface?
The file descriptor is created in user space, and is defined to be a
pipe. So both automount and systemd create a pipe, and then pass that
pipe fd to the mount system call.
So it is not autofs that creates the file descriptor for the user.
It's the other way around: the user creates (using "pipe()") the file
descriptor, and passes it to autofs.
