practical consideration: When milling or turning, if I pause to do 'something' I would want to be able to retract the tool in the direction of the tool axis so no damage is done to the tool or the workpiece. Normally on a 3 axis machine joint mode = coordinatemode as far as jogging goes, so there is no difference. But on a hexapod and perhaps some other configs I would most definitely like to jog in coord mode, Z-axis first in general.
Hope this helps the thinking. j.
