I think the first time Eliezer said he couldn’t get into her mind was that he couldn’t understand the psychological state she needed to be in to make that statement.
The second time—where he was writing about what she believed—he was discussing her apparent epistemological state.
There are significant differences between the two for observers. I can almost never understand someone else’s psychological state, but I can often figure out what they are talking about and how they got there epistemologically—that is, what could have caused their stated beliefs.
