So I think we're broadly all in agreement that the notation from the seven clues is a bit off in places (1,2,7) but understandable and done to make them consistent.
The sequence doesn't actually spell what it is supposed to because of the double move of one letter, which is slightly unfortunate, but hard to see how you could get round this.
I still don't see the ambiguity, but maybe I'm missing something. You do the first thing (ETL), then the second thing (PATM), then fill the barred cell, then you're done. I can't see where any ambiguity is.
