FileVault and Bluetooth Low Energy devices at login

In the session it is said that Apple Silicon has a "unified login experience with and without FileVault", made possible by "fully booting macOS without requiring the user to unlock the system".

Does it mean that at login screen after restart the system will connect the Bluetooth Low Energy mice and keyboards? (Currently FileVault On prevents BLE mice and keyboards to be connected before the user logs in after a restart.)
