The paragraph says in part " Jehovah's Witnesses find genuine refreshment through up building Christian fellowship".
The reason the WT keeps repeating this 'required' reaction throughout its literature is to ensure the rank and file continue training their minds to react accordingly, like good little puppies. Thus, at the end of every meeting you will hear a chorus of dubs exclaiming "Oooooh wasn't that a LOVELY meeting! I feel sooooo refreshed!!!" or words to that effect.
Try asking most of them what the best part of the meeting was for them and I guarantee you will be met with a sea of blank expressions. If only there were visible thought bubbles above dubs' heads during meetings I would be willing to bet most of them would include images of work, recreation, concerns about family members, what to cook for tea, what's on the TV that night etc. etc. and a LOT of X rated stuff!! The rest of the dubs would have butterflies and bunnies flitting around in their cloud filled heads as their brains automatically switched to standby mode 2 minutes after the introduction. Of course there will always be the exceptions to the rule who sit there taking notes throughout as examples to all, with their halos shining brightly. The backbone of the Cult bless them!!
In my opinion the only thing that has been 'refreshed' for the majority of the dubs is their collective cognitive dissonance.
