No silly, it means it has a double
winding (wire), each with 11 turns on each pole of the armature. A double winding is made with two strands of wire as opposed to a single winding which has a single wire or a triple winding which has, you guessed it, three wires!
In effect yes, there are 22 turns of wire but in fact there are two windings with 11 turns each connected in parallel (as opposed to saying "22 turns" which would mean a single winding with 22 turns - this would be equivalent to two 11 turn windings in series).
Double and triple windings allow the armature to pull more current (i.e. higher acceleration/brake and/or speed) before the windings are burned out.
The GM Cosmic EvoII team edition is a triple winding but i can't find how many turns. Perhaps you can look it up by the part number (I see 9509 - there might be one digit missing at the end).
