Commits are not replicated from the source cluster to the target 
cluster. You have to manually sent a commit to the target cluster 
manually if you want to see all the pending docs:

curl 'http://target_cluster:8983/solr/collection_name/update?commit=true'

You can also try to configure an autocommit on your target cluster [1]
