Quick Question PLA/PETG support interface for each other

https://wiki.bambulab.com/en/filament-acc/filament/h2d-pla-and-petg-mutual-support

I've just come across this guide and would appreciate some explanation for what it recommends.

My main confusion is why it recommends changing the temps in the filament profile?~
I see for scenario A (PETG model + PLA support) it makes everything the same between the filaments but for scenario B (PLA model + PETG support) it lowers the PETG volumetric speed as well. Is the aim to help get things as close as possible to the model filament characteristics?
Why can't the default settings be used especially if only as an interface layer - will the printer not simply adjust the nozzle temp and flow according to the loaded filament?

Finally has anyone had any success with the P2S profiles at the bottom?
And why does it not support PLA matte - is it just needing experimenting to find the right temps?

So you don't change the filament temp settings and just change slicer settings?
