May have been weirdly cached or something. I've found that if I search the hiltonfamilymvp website and then later go look on the regular Hilton sites, it auto populates the MVP corporate code for me. Not in a way that I can edit (with the numbers) but it just says "Corporate code: MVP" on the left side there. I'm guessing somehow this just continues to happen for previous poster. Maybe he never shut down his computer/browser and it just continued to work or something.
