By Jove, you're right! I completely missed that he used the term "off-hand" in his original post.I agree I and I believe that was the OP's underlying question .
Hopefully, we've now clarified that if you're wielding two weapons (say, rapier and sickle), and using TWF to gain an extra off-hand attack with the sickle, you're stuck using the sickle if you choose to trip with it and thus gain another, "free" attack because of your Improved Trip feat.
But if you're wielding two weapons (say, rapier and sickle), and using your BAB alone to attack twice, you can trip with the sickle and then substitute any melee attack you want when you make your "free" attack gained via the Improved Trip feat.
Hopefully, that's clear.
