going to get out of touch with the code, unless you have some phase where you are going to review them in depth

I think treating comments as something that's done in a separate phase is the wrong mindset. Comments should be integral part of code and therefore change whenever the relevant code changes.

Maybe, but it's not that easy. You're generally going to see a 3-lines-of-context diff, and the reviewer won't necessarily have the idea to read the entire file (or worse, go poking elsewhere in the codebase) to see if comments deserve changing.
