This is due to this code in `calc-read-key-sequence':

      (calc-unread-command (cdr key))
      (unwind-protect
          (progn
            (use-global-map map)
            (use-local-map nil)
            (read-key-sequence nil))
        (use-global-map glob)
        (use-local-map loc))

that intentionally rereads key sequences to translate `Q' to `Й'.
Without jumping through such hoops, it should work as you expect.
