The response from the shards is different from the final spellcheck response in that it does include the term even if there are no suggestions for it. So to get the behavior you want, we'd probably just have to make it so you could get the "shard-to-shard-internal" version.
See http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/core/src/java/org/apache/solr/handler/component/SpellCheckComponent.java ...and method "toNamedList(...)" ...and this line: if (theSuggestions != null && (theSuggestions.size() > 0 || shardRequest)) { ... } ...the "shardRequest" boolean is passed with "true" here if its the 1st stage of a distributed request (from #process). The various shards send their responses to the main shard which then integrates them together (in #finishStage) Note that #finishStage always passes "shardRequest=false" to #toNamedList so that the end user gets a "normal" response back, omitting terms for which there are no suggestions.

Had one follow-up question - how does the Distributed SpellCheckComponent handle this? I tried looking at the code but it's not obvious to me how it is able to differentiate between these 2 cases. I see that it only considers a term to be wrongly spelt if all shards return a suggestion for it but isn't it possible that a suggestion is not returned because nothing close enough could be found in some shard? Or is the response from shards different than the final spellcheck response we get from Solr in some way?
