it works for the bass part because there is no zero pitch-bend event after the upward pitch-bend--only on the guitar part you have one before and after the top pitching.
you must realize that a zero pitch-bend right after any other just makes the former (almost) to a nil effect. iow. you may hardly hear the pitch-bending if any at all (it depends, on tempo and the synth slew rate reactivity, whatever).
no need to punctuation flood :/
