It sounds so hand-wavy. I'm guessing she (as well as the entire food chain from her keyboard onwards - the DSPs to the SSPs and the publisher websites) would be sleeping under a bridge if she was paid for actual conversions, rather than for just filling a purchase order of impressions with whatever she can get.
Sometimes I wish I could get clients with loose wallets like this...

That said, it's quite possible that the article mistook 'hit rate' for 'conversion rate'. That would explain why snooping for imps "near bank branches" would make sense. Those customers may be primed for the ad/can convert sooner.
Programmatic ad sales relies on collecting incredible amounts of behavioral data and letting advertisers target upon numerous criteria. Trying to get someone to sign up for your credit card? Perhaps try advertising to a 20-28 year old male who's hit up both a few debt forums and a few gadget review sites lately? It's all pretty amazing from a scientific POV.
