community rollout strategy trailhead

Is this a typo in the trailhead or am I misunderstanding the text?

One of the Important boxes states: The default external access level must always be more restrictive or equal to the default internal access. When you’re setting up your external org-wide defaults, you can’t give your community member more access to an object than you do to an internal Salesforce org user. A best practice is to always have external org-wide defaults set to private.

Step 12 states: Choose an access level of Read Only or Read/Write. (If the object’s organization-wide sharing setting is Public Read Only, then only Read/Write is available.) 

These seem to contradict each other. Shouldn't Step 12 state "If the object’s organization-wide sharing setting is Public Read Only, then only Read Only is available"?
