Nothing mentioned, you are confused, no where mentioned like that, If you have valid Canada PR status, and PR status will be in good status in future, then no risk of staying out of CANADA.
Clear cut mentioned in CIC website that applicant can stay of CANADA as long as he wish but his PR status should be in active or good status. Link

I agree to what you said in the first link. I also read the below comment in the second link I pasted, so maybe need to raise a web query...

"While we process your application, contact us if any information on your application changes or if you:

Thanks and have a great day!
