I have come across, more and more frequently, that writers move the verb forward in sentences like: Today some English teachers attend to grammatical niceties in a more analytical way than did their predecessors

in stead of

...than their predecessors did.

Is it an American/British difference? What is the King's choice (assuming he speaks the King's English)?
