L86 Hardware Design PCB

Hello, good morning.

At the “L86 Hardware Design” reference, on page 32, What does “interfering vias” refer to? I understand that GND vias do not apply. And regarding the area, does it refer to the 30x30mm square around it, or to a different/smaller area?

Thanks in advance, Juan
