So, I'm of the mind that H.R. Wells is pulling a Berlinghoff Rasmussen and is trying to gather technology and scientific research from S.T.A.R. Labs to bring back to and advance Earth-19, which in the comics is still stuck in a Steampunk-y Industrial Revolution technological level (it's the site of Gotham by Gaslight). Not that The Flash has to adhere to the comics perfectly, mind you.
The way he says his name is evocative of H.G. Wells, which fits his novelist cover story but also gives him ample excuse to ask all kinds of questions about their science and technology without suspicion, now that he's come out with the "truth". It could also foreshadow both the technological era he comes from and its Steampunk qualities, and could also be telegraphing a "War of the Worlds" between universes.
It would explain his complete lack of knowledge of their technology and some of his anachronistic phrases.
There have been several stories that have involved H.G. Wells himself (or herself, in the case of Warehouse 13) being a time traveler and that being the basis for his books, so it could just be Wells mining the alternate universe for story ideas like he says, but I'm still counting on their being something shifty about this guy.
