Automatically update style?

Hi everyone,
I'd like to ask a question in MOS Word expert,, so the question is :" change line spacing of style HEADING 1 into exactly 12 pt and then apply to all Heading 1 style".
So I just modify the HEADING 1 style, and then check the box " Automatically update". So is it true or false?
Because, when I do it again at home, although I don't check the box "Automatically update" but all texts that have the same style "HEADING 1" in the document still change into new.
So what is the difference between check and not check the box "Automatically update" when I modify the style?
Thank you so much.
