Since I saw a lot of views (and no responses), I figured I would follow up on this.
I asked the question in an electrical forum, and got several responses. Even some of the mods gave incorrect responses at first, but the eventual consensus was that No, I did not have a hot neutral, and the fixture was wired correctly.
Specifically, when wiring a 3-way switch where the power goes to the light first, the white and black wires coming from the switch are interchangeable. Both are hot, and either can be connected to the black power source, or black from the fixture. Just make sure to tape the white black to indicate it's no longer a neutral.
