C'mon Peter, if you haven't got an electronics background then chip data sheets are rather heavy going.
In answer to the original question I believe (and may be completely wrong) that the 500 KB program limit is because programs need to be able to fit in the ARM microcontroller's flash and not the additional 32 MB RAM. I can't answer with regards the video other than guessing from Peter's answer it is a limit of what the microcontroller can drive.
