Yes, of course, 'execs' don't manage anything on their own, but the OP is talking about 'email retention' in the context of litigation and discovery i.e. 'a copy' irrespective of label, which is a legal requirement.
Eric Schmidt is not deleting his emails after 72 hours for the reason you mentioned and certainly the company is not, which is the salient issue.
One could say 'oh that's just from his inbox' but that's pointless in the context of this conversation because we're talking about 'If the corporation has a copy or not' i.e. 'IT' etc..
Scmidt deleting maybe a local copy after 72 hours doesn't really have anything to do with anything other than his personal email habits.
