"Under certain conditions, macOS 11.0.1 and macOS 11.1 hosts are requesting the update server send the 11.0.1 update, instead of requesting the next available one."
I can reliably reproduce the issue by asking the MDM to list updates on the client. That puts the device in a bad state until the next reboot.
But even without the MDM taking action, the client can enter this state as long as it's enrolled in the MDM. My guess is there a background download/check that happens at an unspecified interval.
