Can I Delete Install Mac Os Sierra App Store Download

I have downloaded the updated macOS High Sierra installer app from App Store, in order to put it on a pen drive, in order to have a backup installer for the os, just in case issues occur.

I do not think those things are true but, just in case, I am asking here: are they true? Do I need now to re-install on my own Mac the OS, if I have downloaded the High Sierra install app and deleted it? Or do I need to download it again and keep it there?
