So nothing JR related earns any points? Just transactions outside of transit?

I thought purchases within JR would have counted as well, regardless of whether it is at a vending machine or tap and go. For example, if you buy a ticket at a vending machine for 800Y that should, in my mind, be 4 points and if you tap in/out within the system for a total charge of 800Y that would be 4 points as well. If I understand you correctly, no transactions with JR earn points (so regular commuters who use JR lines with their SUICA card would not earn any points associated with the transportation element of their commute)?

Just so I understand correctly:

Hiro Protagonist gets up and heads for work at Pizza-La. He heads to down to the station and buys a coffee and a snack from 7-11 for 400Y with his SUICA card and heads down to the train. He taps in and rides to his destination and taps out, which charges 200Y to his SUICA and then walks to Pizza-La.

Would he earn 2 points or 3 points for his commute to work?

Again, thanks for help in understanding this. I think it's really interesting.
