Churning it would help the seller create a fake sense that there are real buyers chasing the stock other than the seller. The seller keeps buying and selling stock to himself to entice other buyers to increase their buy prices. The recent run from 38.5c to 40.5c might just be the buyer buying back his own stock. This will gradually draw in other buyers from much lower levels right up to 40.5c.
Once he has enough buyers stacked up, he will drop a big load of shares wiping out several lines of real buyers at the same time. So churning it can help the seller sell stock at higher prices.
All speculation from me there.
Apologies for not being gender agnostic.
