No - parallel output doesn’t get automatically enabled - you have to specify using it with one of the WS2811_PORTxxx variants.
Also I’m not sure how well the esp8266 parallel output code is working right now
@Daniel_Garcia on calling individual controllers, this is causing unexplained flickering for me. I’ve given details on a new thread to avoid mixing too many things: https://plus.google.com/+MarcMERLIN/posts/hzMDbNwVYjY
I anyone reads this thread and wants to do separate strips, so far I’ve been doing FastLED.clear(), but this clears all separate strips.
FastLED[1].clear() does not work, the way to do it in this case is
FastLED[1].clearLedData(); (found in controller.h).
@Daniel_Garcia if you add me as editor to the wiki, I’m happy to make some doc improvements 
I’m also happy to help triage/close some open issues.
