I'd bet $50 you're their second choice but their first choice hasn't given them a firm yes yet, so they're keeping you in reserve. I'd carry on looking in that situation.
I agree with the recommendation to keep looking for a job (since this is a promising low-likelihood opportunity); there are other likely scenarios:

- The advertised position isn't certain; factions within the company might not want to spend money for a new employee (or for someone else's employee in particular).
