I love it. That is optimal contact. I guess you can compare it to training in water. The atmosphere is so thick with contact that any movement is felt throughout.
The attacker, the uke, the floor, the ceiling, the walls and the air molecules that connect us all within the confines of the room.
My belief, my search is that in such a connectedness, "blending, grasping and manipulating" goes beyond the simple passing of the hand, the hip or the shoulder. It begins with the intention of the mind, with the idea that the mind can be extended beyond the boundaries of the body...thus internal energy becoming external energy.
