With SolrCloud, there is no such thing as master or slave.  When you 
index documents, all applicable shard replicas are indexing the 
documents independently.  I think the simple answer to your question is 
"yes" with the additional note that they are not "slaves" in the same 
sense as what you may be used to with older Solr versions.

With the additional inclusion of soft commits in 4.x, NRT is completely 
achievable in the SolrCloud model.
