I believe that it is the swirling motion that makes it appear that aura is moving towards Gon, and gives objects the same appearance of attraction. He's basically taking aura from within his body and then swirling it around a single point (his fist). He's actually releasing all his aura, and then bringing it back. The swirling is similar to a whirlpool. Another example is Uvo's Big Bang. He's clearly releasing aura, and then it appears drawing it towards his fist.

In all honesty, there's no point in arguing about this. This is like being blindfolded and then poked with something, and then being asked to identify the object; we just don't have enough information, and there are many ways we could be deceived.
