I don't think you need a source to know that either a) they do some automatic "adaptation" of the layout elements; or b) they render it as iOS does. Neither of these scenarios is optimal, nor prone to great UI work.
Anyway, my point concerns more the concept/approach than the exact implementation. "Converting" is proposed as an easy path to have your product on other platform, as opposed to doing all the due work to address differences and specificities.
