Indentations for all results have been removed. "More results from..." also appears to have been removed. It would appear that the algorithm is placing more emphasis on individual pages and less on entire websites.
I believe someone else noticed unclustered results a short while back. It may be that Google is experimenting with various display methods... or it might have simply been a glitch. Google's pushing around a lot of data, and occasionally odd things happen.
