I don't agree that all of the terms on this sample list should be local searches, and I'm sure there are many more that don't belong.
The blog post is about a week old, and Google is undoubtedly monitoring user satisfaction. In the initial Universal Search tests, Google dialed the Universal returns up high to get enough of a sample to normalize results, and I suspect we'll see the same pattern here.
It's likely that Google will find a lot of the queries they're testing aren't in fact intended to be local. I think they'll also find that the map results they're now showing aren't remotely close to satisfactory in metro areas.
That said, as Google points out in the blog post, there is a real problem. Many searchers looking for local results in fact don't enter the local area when they search. AdWords does permit location targeting, so to some extent this might be considered to be an attempt to reduce reliance on AdWords for this type of search. It's also inevitably going to drive some geo-neutral sites down, perhaps lower than many of us would like them to be.
I myself am uncomfortable at how much thinking Google is trying to do for searchers who know what they want, perhaps at the expense of those who do.
