Seems, the latter gets some wrong information as indexversion and generation

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.
