No,i think when he said "my little green friend" and that he has been waiting for this too long ,he thouht yoda lost the duel when he fall..so sidious was going towards him to finish him since he is helpless and can'r defend himself because of the electric shock he got...but when yoda stood back and used the force to kick palpy a**,then he thought i'm not strong enough for this little green thing...lol.only my point of view,anyone agree??
