You're making the assumption that Google would factor in views/CTR when it has modified the title/excerpt which may not be the case.
This is a very logical patent IMO (surely way too obvious to be able to have patent protection?) - I kind of assumed they did this anyway and for years. Maybe not but either way, if it is in play, webmasters need to bear in mind that the META description tag is still indirectly a factor in ranking.
