What it means
The first phase of a DBCC CHECKDB is to do primitive checks on the data pages of critical system tables. If any errors are found, they cannot be repaired; therefore, the DBCC CHECKDB terminates immediately. The next page pointer of page P_ID1 in the data level of the specified object points to a page, P_ID2, in a different object.
