Am I to interpret that this means what the agent did for me will work?

I'm so confused. And I love how nobody KNOWS FOR SURE! That even calling and verifying won't do a thing! That just seems unbelievable to me.

So, I'm going to just leave it as it is. I would call and ask about other options, but since what agents say and do apparently don't mean a thing, what's the point? What if I called back and explained my situation, and the next agent also told me it was fine? Am I supposed to say this: "NO, IT'S NOT, LET ME PAY ANOTHER $100!"

Thanks again for all the input ... I do value all of your opinions, but I'm not going to volunteer to pay an extra $100 when I already booked my flight. I'm going to trust Southwest to take care of it and stand behind what their people do.
