Why is it recommended to have the common wire between 2 loops on a layout tied/be the same? What are the benefits? Are there any benefits to having a separate common wire for each loop? Loops are independent of each other.

Current flows through the common as a return path. Less voltage drop than with one return path.
Well, all of the outside tracks should be tied together if you're using TMCC/Legacy or you'll have control issues.
Thanks for the reply? Can you be more specific on thet type of control issues?
Thank CJack for the reply

The control RF flows partly through the outside rail (common). So if you want TMCC on both loops, you’re going to have the outside rails connected together...either by track pins or two common wires which both go to the common connector on the power source (best).
