Clarify the conditions for Enterprise Users

Why is this change being made?

The original formatting of the Enterprise User section did not make it abundantly obvious that only one of the conditions needed to be meet. In order to address this, I have:

1. Added some verbiage to explicitly state that only one of the two conditions needs to be met
2. Adjusted formatting slightly to make the conditional more obvious at-a-glance

This will hopefully help folks who tend to skim (that's me!) when working quickly, so that they're less likely to get stuck on definitions.
