As an update - trying the experiment today and it was only at page 8 that the "including results..." appeared.
@tedster - could be an effect of semantic search at work indeed (but see later in response). And the fact that pages get 'scored' based on sematics, similes, etc, onpage is, I think, pretty much a given now.
The difference for me here is that it isn't a single set of results based on one search term (whether semantic or not) but the concatenation of search results for two terms, that Google is adding together, and that you get offered the option to SPLIT OUT the 2nd set at some point.
Now it may be that it has indeed been there for some time and I have just never seen the option to split out the 2nd set of results, or it may be that it has always been there and Google has only just offered the searcher the option to split out the 2nd set of results, but I'm wondering if some of the 'sudden drops' we have heard about in peoples rankings for highly optimised phrases (but NOT the 2nd phrase) recently may actually be because this 2nd set of results (semantically chosen I grant you) has now been added to result list.
@aristotle - not sure if you mean the same thing. To me, the experience you suggest sound more like the onpage semantics (not quite working as wanted perhaps) that I mention in my reply to @tedster than the addition of a completely different set of results for a different search term (could be wrong). Did you ever get to see the option to 'split out' the 2nd search terms results?
@lucy24 - as @tesder mentioned, for the moment I 'trust' (as much as I trust anything) analytics to be collecting the actual ORGANIC term typed in (Adwords can be a different beast - but completely different topic :) ).
@sand - this sounds exactly like semantic search at work; probably exactly the way it should. Once again, just wonder as you clicked the results pages did you ever come across anything suggestion you could 'remove' a 2nd result set for a separate search term?
