If a past OS has been downloaded through one's standard Mac/me/iCloud 
account in the past it can be downloaded and installed again. It can 
also be downloaded to install on a different Mac or to archive the 
installer yourself, although this takes a tiny bit of hoop-jumping as it 
is set up to 'download-run-install' with minimal user management 
required.
