Either or/not both do we know when to represent them on the in out chart?

Hi everyone. One theme I've noticed in JY's videos, is that he'll identify a bunch of not both or either or rules, and then chose one to put on the chart. LSAT 36/Sec4/Game1 is an example. He puts the either or, but not the not both rule on the chart. How do we know when/which to put on? Thanks!

    If you have something like X ---> Y, then you are being told that either X or Y (or both) must be included. It is always helpful to place this option into one of the "in" slots.

    If you have something like X --> Z, you are being told that these two variables hate each other. If X is In, Z is Out and vice versa. They both could still be out, though. Sometimes it is helpful to place this option into an Out slot.

    Where it gets a little tricky is if one of the variables (say, X above) is included in both types of relationships. For example, if either X or Y must be In (either/or), AND if both X and Z cannot be In (not both), you theoretically could place the X/Y option In and the X/Z option Out. The reason JY foregoes on doing this (I'm guessing) is to minimize confusion on the gameboards.
