"How can someone who owns millions of shares 'short' something? They arent shorting it, they are just selling it. If you were both short and long a million shares you would be neither. You would be square."
Actually, being pedantic, this can happen in a relatively illiquid market, though it would only typically be IIs that would do it, and usually only in fixed income funds. Basically, they have an asset that they want to hold long term, but in the short term, they need to reduce exposure. It may be because of portfolio balance requirements, or simply because they see a short term risk that they wish to mitigate.
So for a week or month or three months, they might short (in part or in whole) something they actually hold. With a liquid asset, you'd just sell and buy back, but if the asset is in short supply, that may not be practical.
It doesn't make sense to do that in Bully's scenario, for several reasons, including that the short is not without cost, and that to open a short position you'd have to disclose the material fact that you are about to be selling millions of shares. At which point the counterparty would say, "No thanks." And if you didn't disclose it the liability hit you'd face would be substantial. And, it would probably be criminal.
But you can, and sometimes institutions will, open a short on assets that you hold and intend to continue to hold.
