How does deleting the disk image (that you need) help in the installation process? And what would you select instead?
Sorry, this just doesn't make sense to me.

You need to right-click on the 'mounted' ISO image and unmount it. A mounted image moved to trash also unmounts it, but you may not want to delete it.
Some versions of macOS download an ISO every time you run BCA, which means you can remove it.
