Wow, it took me some time to realize what you were referring to :-) The manual (or the reference guide page) is under construction and I didn't finish that page. The sentence about faceting is just a copy/paste relic :) I'll go fix that asap.
I remember a bunch of Jira issues w.r.t NPE and distrib.singlePass which have since been fixed. If you find something else, then please open a issue. The distrib.singlePass approach reads all the stored fields from all shards for all documents instead of just the top N docs. This can be advantageous if you are returning a small number of fields but may cause performance degradation if you are requesting all or a lot of fields. But coming back to this bug, it seems like debugQuery=true is behaving incorrectly for the normal two phase search? Please open a jira issue. This warrants more investigation.
