Gold price, page-9385

So the 34c sell line was taken out a while earlier and the buy line immediately went up to 34c. Fine.
The 34.5 sell line becomes first in queue and has only 300K+ shares, followed by 60K+ shares lined up at 34.5c.
Given that, why would sellers then rush in to re-line at 34c sell? These new sellers have been waiting all morning already, anyway. Don't they want to sell at a higher price?
Can't be short-selling as that would be at lower than 34c. Weird.
