iwd not honoring AutoConnect=false

Hi

I am using iwd 3.8 with systemd-networkd 257.9 on Debian stable (trixie) 
on an amd64 machine.
There is a wireless network with a PreSharedKey with a .conf file in 
/etc/iwd that I do not want iwd to connect to automatically if the 
signal strength becomes better than an alternative.
The manpage iwd.network advises to use

> [Settings]
> AutoConnect=false

I did that, but do not get the desired result, iwd still automatically 
connects to said network.
The journal doesn't mention anything that points to why that is.
Am I missing anything obvious?

Thanks,
-Alex
