This sounds like a riddle.
It is not clear what "your ticket" and "this ticket" mean
or how the ticket is "attached" to your Japan Rail Pass.
Anyway, Japan Rail Pass got redesigned recently to be a magnetic paper ticket.
Therefore, yes, now you can go through the automatic ticket gate (which this poster calls "e-gate") with your Japan Rail Pass.
> Is that where all seat bookings etc would be "loaded"??
No;
Japan Rail Pass has no data of seat reservation
(e.g. train name, car number, seat number, etc.);
they are indicated by your reserved-seat ticket.
When you receive your reserved-seat ticket for your ride covered by your JRP, make sure to show that pass.

The second photo in this blog page
shows a Japan Rail Pass which lets you use Green Car seats.

there can be another option which is better cost-wise than Japan Rail Pass.
