The fact that it's titled something outside of her system of titles says to me that this could be just a side thing, showing off her 'Melissa' side and exploring areas we haven't seen before (submissiveness to the degree of being completely controlled by someone else as well as thoughts about her mother).
That, as well as the fact at least half of this is confirmed as older material, makes me think the next project will return to the numbering system and this is simply an 'unreleased collection' for want of a better expression.
But to me the fact that this has been billed quite a few times as EP3 makes me think that she deliberately decided to change its name. I wonder why tho - I hope she changes her mind
