Hey Jaron
Item, grasp his left hand with your left, and jerk it toward you, and throw your right arm from outside over his left, and grasp his right arm with your right hand, and step with your right foot before him and swing him to your right side; thus he falls" Forgeng translation Meyer pg. 244, 3.13v.4
I think there are couple thing's to look at to make this work, Balance your's and his, surprise you surprise him.
1. grasp his left with your left, jerk it toward you...
This is the initial move when you grab his left with your's and pull it towwared your left side I think a step back would help, he will most likely pull his left hand back and try to grab your left hand with his right hand.
2. and throw your right arm from outside over his left, and grasp his right arm with your right hand...
when he is grabbing at your right hand with his right hand reach over his left arm and grab his right arm /wrist.
3. and step with your right foot before him and swing him to your right side; thus he falls"
He is pulling his left arm back grabbing at your left wrist, hand, arm, you should be
feeling remember Weich Und Streich when he pull's back hard go a little weak when he is a little weak pull hard on his left arm and push on his right to break his grip and pivot on your foot to pull him froward and over your right leg.
all this is situational, if your timing is off it isn't going to happen, he might even throw you backward's over his leg Speed, surprise, and strength is critical, here are a couple of other example's which are similar not exactly the same, i think it will help you see what Meyer is talking about though.

Von Auerswald Pl. 26 3. Petter under the section titled "The seventh part" number 6
Petter illustration these are variation's I think of what Meyer is doing, same hand gripping same hand ie. right hand gripping right hand, left hand gripping left hand, across the body turning to drag there arm across your chest, Keep in mind these are are not magic tecnique's that are full proof and work all the time everytime, not everything Meyer does will alway's work the same for you he may have been taller, stronger, shorter, faster some of his technique's may work great for you and other's may never work for you whatever the reason.
