No, the Y axis moves during Z lift during G28.

Issuing an M114 after a G28 gives me:

>>>G28
SENDING:G28
>>>M114

X:0.00 Y:0.00 Z:10.70 E:0.00 Count X: 0.00 Y:0.00 Z:10.70 (still using stock marlin without enhanced bed levelling)

Issuing a G29, the LCD reports first probe position as X0 Y37. Pronterface reports Bed x: 30.00 y: 30.00.
