Last Minute (self or bot) Upvote - Voting within x (12 - 24) Hours of the end of Active-Post Period of 7 days

In reference to:

https://steemit.com/bots/@abusereports/last-minute-upvote-list-2018-02-22

What is all the fuzz about last minute voting?

I still don't get it and especially after reading this:

https://steemit.com/steemit/@calamus056/curation-rewards-explained-in-great-detail

Where can I find anything about the pro's and con's of voting on day 6 - 11th hour - just before the post and rewards will become "inactive"?

Anyone?
