The "Full" version is for organizations that have not licensed the platform in the past.
I have also seen situations where Microsoft applies the From SA pricing to a single component. If you only covered Windows with SA, for example, that will get the From SA price, while Office and the other Office 365 components will be priced as "Full" products.
I'm not sure about the tenants, but I would think that each tenant would require its own subscription.
