There is no one shorting a trip zero stock. First of all, no brokerage would let you. And who on earth would short a .0004 stock in the first place? At $2.50 per share margin, it would cost $2.5 MILLION dollars to short 1 million shares of this stock, and if it went to .0005 you'd be screwed. No one in their right mind would short a stock that can go up or down 25-50 percent in one click.
MM's of course, do short - but they generally cover within microseconds. If they don't cover by close of the day, THAT goes into the short interest column, which is reported twice per month to Finra. It is virtually meaningless - it cannot be used for ANY kind of leverage - it only indicates that the stock is trading.
