Bypass used on Turretboard.com layouts?

[Focalized]

I'm curious about the bypass often used on some of those layouts. 

Like this one. With the two cross links and the use of the LED resistor on the switch like that. It's very uncommon from what you usually see.

Is it better in any way?

Also a side note on those turretboard.com layouts.

A lot of them using PNP transistors will have the power wired up negative ground. I'm confused. Do some designs have PNP transistors but use negative ground power?

Like this one.

The bypass in your first example is the type of bypass where the input of the effect is grounded in bypass. Here's an example of it that lots of people use http://www.generalguitargadgets.com/pdf/ggg_sw_3pdt_tb_gi_dcj.pdf. The only difference is that the turretboard layout is using the switch to mount the LED resistor, I guess this saves having to mount it on the board.

I believe the "resistor on the 3PDT" method is used by David A. Main when he builds sub-mojo/practical pedals with an LED. Since many of the original turretboard.org layouts were D*A*M pedals, it makes sense they've posted that offboard schem.

I've have also previously spotted the postive ground/LED power direction reversed on at least one turretboard.org layout over at 'tother place: It's not a problem - if you spot it in time...

The turretboard guys are great people, by the way.

I'm going to try it.  Wondering why I've never seen it posted anywhere else, nor seen a build with it. It seems really convenient to have the resistor on the switch.
