I agree with you that there is a lot of room for ambiguity here. I'd imagine their target are e.g. architectural studios and advertisers, but how much interactivity is too much or whether this is separated by the platform a UE project is distributed by are questions that need to be clearly answered. The fact that, after the recent communication issues/attempt to pull the rug over the entire industry (depending on whom you ask) by Unity, Epic didn't prepare a detailed and easy to understand page explaining this topic in detail, rather announcing this in a speech, is somewhat disappointing and shows an apparent unwillingness to learn from their competitors missteps.
