This is a cute story but according to the
Constitution one does not become President until taking the Oath of Office.
The President is an office, not merely a rank. Being the highest ranking official in the government is not enough to make you President.
Agreed. I think it would be more accurate to say that there was no sitting President during that time, but that if some emergency had required the presence of one, he could have been sworn in to the job for that purpose. --LDC
