This video gives a good, brief explanation of Relational Frame Theory (RFT).
FIML practice can be understood in terms of RFT. What FIML practice does is give partners immediate access to their neurotic “relational frames” of reference, their mistaken interpretations. When we see a few times with great clarity that our neurosis is based on a mistaken interpretation (a mistaken relational frame) of what our partner actually means or meant, we will be able to change our relational frame (correct our mistaken interpretation) without much trouble.
FIML works especially well for making this sort of change in relational frames because it deals with those frames the moment they arise, while they are still just starting to be accessed. FIML also works well in this respect because it is based on real data shared and agreed upon by partners who trust each other.
Here is another article on Relational Frame Theory.

Note 10/12/19: In terms of RFT, FIML practice could be defined as a practical application of RFT during unique real-world situations that arise in a unique relationship between two (obviously unique) people, each of whom speaks a unique idiolect.
The results of FIML practice are therapeutic and include: deeper understanding of how partners speak and listen, how their psychological frames function and interact, how and why they make mistakes in understanding each other, and how to correct those mistakes.
FIML can be done with zero knowledge of RFT. If exposed to RFT after they are good at FIML, partners may find that much of what they have learned could be described or outlined in terms of RFT.
An advantage FIML has over RFT in practical applications is partners will discover their own frames in their own contexts without any need for a theoretical outline or explanation of them.
FIML needs very little theoretical structure or explanation to work. By simply using the simple rules of the FIML “game”, partners will find themselves immediately engaging with their shared and unique relational frames.
There is no need for further guidance once partners understand FIML rules and know how to apply them. All discoveries made after that point will be unique to them and under their own control.
Their discoveries will have wider application and will help them with other relationships. And while many of their discoveries could be generalized to all language or all psychology, it is not necessary for them to do that.
