Why do microwave transformers have one side of the secondary winding attached to the transformer core?

Microwave transformers have one side of the secondary connected to ground because the magnetron tube's case is grounded. The other secondary lead is connected to cathode of the magnetron via a diode rectifier.

This is a insulation winding ( just one layer) to separate between the primary winding and secondary HV winding.. The iron core is connected to the earth grounding line.
