Yes, exactly.
And if you’d use EasyRide (or Checkin/Checkout in the ZVV app), that journey would cost 2.90 instead of 3.20 each (= 1-2 zones half fare), which makes 344 days. 🙂
But you can use that HFT Plus credit also for personal tickets for any other train or bus journey in Switzerland as well. This credit will appear as additional payment method in your SwissPass/SBB account and in the SBB Mobile app, just don’t forget to select it (switch it from your previous payment method) before buying tickets.
