Yes, I'm pretty sure this is all it does. A cable that is normal data=20 and press a button and it is a cable that is highcurrent charge capable=20 (signaling via pullups on D+/D- lines in some manner). That this trick=20 only works on suitable USB ports is not mentioned or at least buried=20 somewhere. But hey, the cable looks fancy!
