level left wrist and uncocking

[dlam]

when the left wrist cocks the right arm bends. there is no cocking of the right wrist

How can there be no cocking of the right wrist? The right hand is located below the left hand. When the left hands cocks the shaft I presume that the right wrist is cocking too.
The only way the right hand is bending when the left hand is cocking is if the left hand is super strong grip and the left hand is super weak and no longer parallel to each other.
