“And you think it’s a coincidence?”
The are more alternatives than a): “coincidence” or b): “Q is confirmed!”
For example, these are also alternatives:
c): “Assange created ‘Q’ as a publicity vehicle, like a number of previous publicity stunts he has done in the past”
d): “Assange has nothing to do with ‘Q’, but just inserts phrases from Q posts into his tweets because he realizes Q followers will think he is connected to Q, and that will gain him more publicity”
you are the only one here that is making a rational counter argument.
