Well, I would agree with that. But it doesn't indicate a major change in strategy, merely replacing problematic chlorine sources with our fav...bleach.

My own closing routine is, of course, get everything (in the chemistry) clean and balanced, wait till the water temp drops to 60 (65 max), raise FC to shock level. Add 1 qt 60% poly, wait 48 hours, then test and raise FC to shock level again...then close.
