Hiring Processes: A Question

I recently had a positive experience with a hiring process. I completed one interview and was even referred to another position, where I participated in two more interviews— the final one being with the director. It went well, and I was informed by the recruiting team that I was a top candidate and would hear back soon.

However, I noticed that the same position I applied for has been reposted as new just last week. Now, I find myself with three applications for the same job title. Is this common? Does anyone know why a job I applied for would be listed again as a new opening? How should I interpret this from a recruiter’s perspective? Is this typical practice?
