That makes a lot of sense in drawer construction where you have a long 
divider cross-grain to a the cabinet depth. Minimizing cross-grain 
forces is certainly desirable. But I would have thought that the 
cross-grain dimensions are so small in most M&T joints, particularly 
with stub tenons, that the forces involved would be quite small. I guess 
only gluing the shoulder end of the tenon helps prevent a gap developing 
at the shoulder as she stile expands & contracts. Better safe than 
sorry, I suppose.
