I should have done a little googling before I posted this question. It seems there about a gazillion postings on this subject, and the overwhelming majority says that the 2 films are the same. It appears that Freestyle submits a large, annual order for it, and then Kodak makes a large, single shipment each year. No advertising costs for Kodak, no warehousing, just a one time large shipment, so they can sell it at a substantial discount and still maintain their profit margin. That's the best answer I've found. True or not it makes sense.
What DOESN'T make sense, and this sort of thinking is probably why the Kodak company is in the shape that it's in, is aren't they just cannibalizing their own Tri-X sales? If I can get the same product for around half price, why would I buy the one priced twice as much? At some point don't you kill your brand? This is probably why there is no out and out confirmation from Kodak or Freestyle that yes, this is rebadged Tri-X.
I'm still going to continue to buy the Kodak, either because I'm just stupid, or I just like the bright yellow box and the idea of shooting Tri-X, or because I know for sure what I'm shooting is Tri-X and I like being connected to what I think is the most legendary B&W film around. You can go back and look at all the photographers who shot it and it's quite a group. Maybe all of that. The main thing is it seems everyone agrees the 2 films are the same. How Kodak runs their company is out of my control, as are most things. At some point I'm just going to buy a ton of the stuff and put it in the freezer and have one less thing to worry about w/ my photography.
