Yes, the plywood is doing most of the work but it can not do the work as well if the joints are not clean and tightly done. End grain gluing has very little strength. The glue however does give a certain tightness to the joint and also provides a moisture protective coating. The tightness of your joints and good glue spread will minimize the possibility of the plywood flexing or twisting under loads.

This morning I was working on my aft inner spar and I dropped it. I don't have the web skin on it yet. After inspecting it I notice half of my vertical members had broken glue joints. All the brakes had wood stuck to the epoxy so I new they were good joints. But way did so many brake? Does the 3/32 plywood add most of the strength? I know about load transfer. But really.
