Master info gets listed as soon as the replication handler has started. If that core has ever been used as a replication target since the last restart, then it will show the slave information as well. On the last restart, your current leader probably replicated itself from the other replica, which would have been leader at the time. Your other replica has never (since the last restart) been used as a replication target, it has only ever kept itself in sync by doing SolrCloud distributed indexing. There is a bug in the replication info display, fixed in 4.3. The bug info says it affects version 4.2, but I would not be surprised to learn that it affects all previous 4.x releases as well. This doesn't cause any actual problem with replication, just the confusing information on the slave: https://issues.apache.org/jira/browse/SOLR-4661 The 4.3 release is on release candidate 4, hoping for a release just after Lucene Revolution 2013 ends.
