How am I getting 200/20 with SB6141?? - Time Warner Internet

This question is about "How am I getting 200/20 with SB6141??", with Time Warner Cable internet and apps. I upgraded my internet speed last night from 100/10 to 200/20 -- under the impression that I would have to then get at least a 16x4 modem to access the higher rates -- but every speed test I try shows I'm in fact getting 200/20 -- (203/22, to be exact).

Even TWC's compatiable modem page says the SB6141 will only support up to 100. I'm not complaining ..... but how is this working? Just surprised.
