Starting with gdm 3.0, the login session is a failasafe one, meaning
autostart applications are not started up.  This is why your autostart
condition is not meaningful.

With the gdm-shell session, the shell itself includes a menu to start up
a11y functionality when needed. This UI is not present in
gdm-simple-greeter which is the interface of the gdm-fallback session.

If your hardware supports it, the simplest thing to do is use the
gdm-shell session instead; however this cannot be done by default in
Debian. So what’s left is to add the necessary UI in gdm-simple-greeter.
