However, G92 E0 resets the extruder actual position to zero, so the G28 X0 causes the extruder to go to its last known position and it makes a big pile of molten filament.
It's a bug in G28 when used with the X0 parameter CAUSED by the G92 E0.
Remove the G92 E0 and everything works fine,
So, even though the G92 E0 does not IMMEDIATELY cause motion, it indeed through a bug in G28 X0 causes the extruder to run during a G28 X0
