think of it as 2 parts
1 part is msg to your audience, sometimes requires deletion to deny shills
some audience msgs don't need to be deleted if they are tame
msgs you don't want shills to see later on can be deleted
2 part is History scroll; if some1 finds your posts interesting they might scroll your account and might learn a lot of History going back and back
