Seems, the latter gets some wrong information as indexversion and generation is far behind then leader. But core index seems up to date and healthy. Why such things could happen on some replicas? (Most of the replicas retuned the same information by both commands) Is information returned by Replicationhandler not applicable to tlog/pull replicas and is not reliable ?
SolrCloud does not use the replication handler in the same way that master/slave replication does. It "manually" initiates any replication that takes place -- the replication handler is not in charge. You cannot be sure that the indexes the replication handler thinks are master and slave are in fact the indexes that will be replicated next. Just ignore anything that the replication handler tells you. It may have absolutely no bearing on what's happening.
Was indexing happening when you looked, or was it entirely stopped? If indexing is ongoing, you may have seen the difference in the index versions in between data being indexed on the leader and the time that the replication is initiated.
