I understand your confusion: you simply don't "see" the way Finder does. And there's nothing wrong with that.
But I get the impression that you want justification for his statements being different from yours. If this is yet another case of poor English, then that's that.
If it's not, then my twopence on that is this: as a musician, if I were trained in only reading the Treble clef, I'd go nuts reading music written with an Alto clef. Some people are unable to accommodate their view of "where the notes should go" vs. "what the notes mean" in a different environment. This, of course, doesn't mean there's a "musical deficiency" on their part, but going about and saying that "I don't understand what is it about the Alto clef that is so important to you" when all you can understand is notes written on the Treble clef, that doesn't mean there's anything wrong with music written after an Alto clef, just that it accommodates somebody's needs other than yours. Shoehorn-fitting everything to only one point of view is not going to make you understand the other ones.
But it doesn't mean there's anything "wrong" with either of you. One insisting that the other is, well, that's another matter.
If this is not the dilemma here, then, ok, it's a "language thing". 😱
My twopence.
