 From what I've seen on the web not even that:
Unlike the original Jefferson wheel these toys are not
intended to choose any row, but to use the row directly
under the plaintext row as cipher text. Instead of the
line indicator from Jefferson, they have a sliding
bar with two windows for two subsequent rows.
