What do you mean? It does not have pads on both sides.
It may look like the pad could be on the either side from a mechanical point of view when looking at the keyboard. But nothing about the system is designed to handle that (neither firmware, mechanical or electrical).
There also isn't an easy way you could mod the keyboard to have the pads on the other side, so I don't think it's accurate to say there are pads on both sides.
Maybe we could add that note to the mechanical documentation? The only case where you need to know about this, is when you want to build your own module.
But really on the other side of the module there isn't enough space to put a microcontroller and pads 😅

I've tested the firmware logic and found that it does not handle the
two possible pads for the keyboard symmetrically. This patch updates
the spec, but another option would be to patch the EC firmware to
recognize keyboard-sized modules with their primary connection on
the right hand side.
