Normally we do not discuss specific query terms - however this one is generic enough that we will make an exception.
I see the same thing, and I've never seen it bfore. Assuming this is indeed intentional and not some kind of Google-gargle, my assumption would be that in this case the query is ambiguous enough that they want to show the "related searches" sooner on the page - so the user has a chance to refine or disambiguate their query.
Google wants to get people to their answer quickly, and if the query has a history of being too ambiguous, they certainly have the ability to measure that and throw a tag to change from the normal SERP. Just as there was QDF (for query deserves freshness) they might have something like "QDD" or query deserves disambiguation.
I'll keep an eye out for this kind of thing to see if we have a pattern or an oddity.
