That's correct, but according to the comments to the issue SOLR-2066, "counts returned when using field collapse are only accurate when the documents getting collapsed together are all on the same shard" (it's actually a quote from SOLR-2592). Which sounds like SOLR-2592 will make distributed field collapsing complete.
It's a pity there are no plans to make the same thing for joins: since SolrCloud by definition a distributed system, being able to "join" only on a single shard makes this feature much less attractive...
