PCV catch can and/or CCV catch can, why both?

What in the world is happening here with B58 catch can (CC) setup ?

Definitions correct? (courtesy of Radium Engineering for B58 catch can)

PCV catch can - runs inline between crankcase ventilation valve (on the engine block) and the turbo inlet pipe

CCV catch can - runs inline between crankcase vent tube and turbo inlet pipe

WTF ?!

Is anyone running a PCV catch can, according to above definition?

My understanding has always been what above definition calls CCV catch can to be the PCV catch.

Picture below to identify where the above definition of dual catch cans are calling out each,
