What is the reason to have the screen unconnected from its voltage or
switched?

The bleed resistor is not part of the power supply. It is installed
close to the tube itself, connected directly between the screen grid and
ground (cathode). Its purpose is to prevent the screen grid from
floating unconnected during the few milliseconds while the screen relay
contacts are in motion between the RX and TX positions.
