Okay, so for the SMTs, you would be earning both? Im still trying to understand those!

Not a guarantee so the answer to your question is "perhaps".

However, think of posting a video on DTube...that video is posted on there but also shows up on Steemit in your blog. Some are commenting and upvoting for the video from DTube while others are hitting it on Steemit. Who pays? Perhaps it is a split. Certainly both DTube and Steemit have an interest getting the tokens in your hands....as part of their reward pools.

Just a possibility.
