That’s not what that policy is about. It was set up awhile ago because some TR2PR applicants got refused PR only because they were outside of Canada. When IRCC realized that their delays were causing people to lose status &/or return home, they put in a variety of temporary policies extending work permits, not refusing applicants for being out of Canada, etc. However, for those who had already been refused PR earlier in the process for being out of Canada, they created the policy you quoted to allow the applicant 60 days to confirm that they would like to reinstate their file and continue the process to receive their PR.
When you receive your initial PR email, you will be asked for the following info:
Name:
UCI:
Application #:
Email for the Permanent Resident Portal:
Original entry date (YYYY/MM/DD):
Date of last time you entered Canada (YYYY/MM/DD):
Location of where you last entered:
Are you currently inside Canada? (Yes/No):
If you are not inside Canada, when is your expected return date?:
If you are not inside Canada, please specify your current location (city and country):
Answer it truthfully as soon as you can (there is no reason not to), try to return by the date you provide, and when you return, confirm with IRCC that you have returned so they can restart the PR process. I would return as soon as reasonably possible.
