There is certainly one solid reason why he would be concerned about shorts. If he has any plans on issuing more shares into the market in order to raise capital, then obviously he would want a higher share price when he does it. I'm not saying that he plans on doing that, only he knows for sure. But it could be a clue as to why he is concerned.
Agree that the short issue may be made up, or something he may have thrown out there to get whatever pain in the ass investor off of his case. They need a professional IR firm to handle that crap, let the Man do his job.
