Handwiring a Kailh Choc keyboard

I'm trying to handwire a Kailh Choc (PG1350) keyboard by doing something like this: https://imgur.com/gallery/87LfDVI

It seems like the diodes goes into the rows. (I wonder if they can go into the columns instead?) 
Here's the diagram for one particular Choc switch: https://kailhswitch.com/Content/upload/ ... df?rnd=945
My question is: to which of the 2 pins do I attach the diode: is it pin 1 (in the middle of the switch) or pin 2 (the one on the side)? Or does it not matter? 

Bonus question. The following guide says the Choc switches can't be soldered directly into a PCB. Is that true for all PCBs? If so, why?

It does not matter. You can connect row-switch-diode-column or row-diode-switch-column.
You can choose any two pins on the switch. The only thing to worry about is that the diode is connected the right way round, so that it lets current through in the right direction.

Nope. Choch switches can't be soldered directly to the Sofle keyboard because the Sofle keyboard uses switch-sockets, and it is the sockets that are soldered to the PCB.. There are other PCBs, made for soldering Choc switches directly to them though. And Choc switches have fixing pins, so you may not even need a plate with one of those.

Thank you so much!
