Definitely perplexing.
I searched old permit files and threads, and couldn't find the original one for the second floor demolition. This one is indeed new, and the permit itself wasn't accidentally re-filed because - as someone said - it was filed, stamped, signed and recorded today.
The company doing the work is Central Environmental Services, which is a major demolition company. They don't mess around with tearing down sheds or landscape beds - they destroy buildings.
The address definitely puts it in Tomorrowland. Main Street East is all in the 1300s Monorail Way.
It's very unlikely, but possible, that they'd submit a permit with the wrong data on it. It would have to pass in front of MANY eyes before it got to the point of being recorded. Someone along the way would notice what it said for the address and description, since those are two of the most important fields on the application.
However, I would find it hard to believe that they're actually going to tear down the TL skyway building - at least not yet. Those are the only restrooms in the land (excluding Cosmic Ray's) and they just invested a ton of money into the partial demolition/remodel. They don't have any sort of contingency in place, so if this permit really is for the demolition of that building, it's significantly premature.
Then again, it COULD be for "selective demolition". I would find it hard to believe they'd involve CES for something minor (they'd do it in-house or with locals).
A good find, nonetheless, SeaCastle. I officially posted today's permits, with this included.
