Yes, Zabadak, I pretty much agree with that. I'm assuming that the later quester belongs to the late 1980s, and found the two negotiated items BUT... as you say, they don't match up with the discarded letters.
As for the highlighting, I'm wondering if we're looking at a variant spelling (specifically, the fourth letter), from the original language. There is slender support for this online, but this would give us two cells touching at corners and the shape resembles the object.
I hope this isn't going to be another hare...
