Reposted job opening after I accepted offer letter

Received and accepted offer letter for a new job. But the company has reposted the same opening again, after 10 days of offer letter acceptance. What does this mean?

There may be multiple openings of same nature in the department, or in another adjacent department

Seems like the case. It's for the same role but a different division. But should I be alarmed and check with HR? They promised they cannot revoke offer letters due to law.
