Wow. Very poorly written I'd say. I'm not certain what I think yet and could be convinced either way, so I'll wait for official clarification from Wizards. Maybe they'll see the discussion of this popping up everywhere and include an example in their next video of the Phandelver adventure to answer the question, or just post something official somewhere.
It's not poorly written. It's poorly interpreted. Anyone that reads the Short Rest rules should know exactly what the feat means. The problem is, people don't want to go read them.
