The Bonan-Jeener's triple Klein bottle is not equivalent to the Boy's surface, as can be ascertained by the fact that a 120° rotation of the triple Klein bottle around its axis of symmetry yields no fixed point, whereas a similar rotation of the Boy's surface does yield a fixed point, which is its "umbilical point" as it were.
