I just spotted this email - missed it before somehow.
In my experience, when you have 8 billion or so web pages and tens of thousands of advertisers, this sort of thing is bound to coincidentally happen from time to time.
But I assure you, the two things are not related. AdWords is entirely independent from the search results, and vice-versa.
(And, as I see you're new to the Forum, I'll just mention that I've worked for AdWords for just a few weeks shy of three years.)

Oh my. I must have a worse case of tired-brain than I thought!
(I'd just been scanning a bunch o' emails for trends, before coming to WebmasterWorld - must not have fully shifted gears...)
Nice to see your name here, Shak. Hope you are well!
And thanks for the laugh. ;)
