The cited paragraph concerns the generalized muscle atonia during REMS, which
excepts eye movements and respiration. It limits body and limb movements
to the fast twitches that presumably are due to overriding vestibular
nucleus output. 
I do not understand what you try to prove about eye movements by citing
the paragraph.
