BUT
{!sobj_LoopedAccount.Owner:User.Email} is what you want with polymorphic owners, like Cases
Non-Pasta version - if you reference a polymorphic field in a scheduled flow, you MUST specifiy the type of relationship you are trying to follow - assuming that only one type of relationship will exist due to a pre-existing query will not work.
Even more succint: when following a polymorphic relationship, you should always specify which relationship type you are following.
