So maybe one way of thinking abut the question is: why are the Prime semantics for picking different? Yes, but the 35s doesn't let me create a formatted expression, which is how this issue arises. The question is why I can use the Prime's "template" to create an algebraic — actually I guess "textbook" — expression which I can put on the stack and evaluate (and even perform operations on in the same way as I can on an RPL model; e.g. I can follow the creation of the expression with [2][+] and get the expected textbook formatted expression as a result); but if I pick it and press [ENTER], I get something that's considered invalid and can do nothing further with.
