It is plausible that the software stores recent imagery in a circular buffer for processing purposes and that the assault caused the software to crash, leaving the data in the buffer. Besides, Steve's work is university funded research so it wouldn't be hard to have the code analyzed if it came to that. Regardless, your paranoia about such devices filming you unawares is misplaced. There are many off-the-shelf recording devices that are far less conspicuous; you have probably already been photographed hundreds of times by such devices. At least with these head mounted devices you have a definite visual cue that a camera is pointed at you. A reasonable practice is to assume you're being filmed when not in a place or around people you trust.
