You're right, there is no indication that Disney has given orders to Kitsis and Horowitz. I'm thinking that something like that is probably more of a "Gentleman's Agreement". Nothing formal, nothing in writing, just an understanding between 2 sets of professionals on how to best handle their intellectual property. If for no other reason that mutual respect, I would imagine anything major A & E want to do with Anna and Elsa is at least discussed (informally) with the original screen writers.

And obviously, they have made at least a few minor (or maybe not so minor) twists, such as Anna and Kristoff being engaged, or Hans being turned into an ice statue. Or Hans, for that matter, launching an attack on Arendelle with the help of some of his brothers. Or the Original Snow Queen, Ingrid, being Elsa & Anna's aunt. None of these events are Canon in the Frozen Universe, they are strictly OUaT Canon.

Having said all of that, I kinda hope that Anna and Elsa get to come back, and can at that point have some additional depth added to their characters.
