I don't see that's there's anything magical about 100%. In a short squeeze, the shorts buy stock on the open market at a high price and immediately return the stock. Some of this stock will find it's way back onto the open market. The shorter can buy that same stock a second time at a different price and immediately return it.
The real key is daily volume vs. volume shorted.
Shares outstanding - about 70M
Daily volume - about 24M
So if shorts were the only ones buying, it would take about 3 days of normal volume to unwind their positions.
But with the price going up, many others are competing with the short sellers to buy shares right now. So volume will go up and/or it will take longer to unwind.
Recently, the daily volume has gone up to 110M shares. A lot of those shares are being bought and sold more than once per day.
There's nothing magical about 100% of outstanding shares.
But it's a huge problem that the shorts outstanding are so high relative to daily volume.
