The RowID are physical location of the data stored on the disk. They are unique for a table. As such they can repeat. If the new record gets stored in the same place (deleting the older one), then rowids would be same (reused).
See this article for details on what rowid consists of in oracle http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/pseudocolumns008.htm
