if you hit the button twice it will upload 2 simultaneously before it has a chance to react and grey out the button, this has happened to me a few times with some PDFs I uploaded. On the other hand if the file is already uploaded it will lead to the same stored file and the second upload will happen in a fraction of the time of the first upload, I assume it does a hash check and just puts it in.

Still though make sure you don't hit the upload button a bunch fast and make sure you don't upload twice when you don't mean to.

Btw here is where your 2 videos lead.
