It is a simple matter of very poor documentation - a confused and confusing writing style. Take a look around the web, there is usually someone who has a clue and has written a clear guide to the camera.
It is quite an achievement to refer to three unrelated issues in around 50 words, so let's celebrate this masterly effort.
And (s)he included an instruction in an asterisked note, hot stuff indeed. So only permit sharp impacts whilst not shortening the battery life by being so bold as to want to decrease shutter lag. Punishable by monitor failure, lol. Got it.
You often hear how educational standards are falling but it is not often you see it so glaringly on display.
I also am impressed by the 'priority is given' bit - how do you give non-IS lenses low priority if such a menu option is selected? That is a tricky business, that 'lens function operation'.
Why not simply have a responsive shutter and take what comes in terms of the battery life, which is affected by so many other factors?
