Don't worry about "erasing" it, that's normal, otherwise, every photo you took on your phone would pile up on your iPhone's "Camera Roll". You can still store this movie (or picture) on your iPhone, because you're downloading it to your iPhoto library, on your mac's hard drive (it's not stored on the mac's "CPU", it's on your hard drive, in iPhoto) and removing it from the camera roll on your iPhone.
You have the option to store it in a more permanent folder in your iPhone's photo library. "Camera Roll" is a temporary folder on your iPhone, for images and movies you've just taken. In other words, it takes care of itself when you sync your iPhone.
It's only "erasing" (removing) it from your iPhone's "Camera Roll" (recently shot photos & movies) but you can select it. Or even set it to automatically do it, by checking the box that says "Last Import", in iTunes "Photo" or "movie" preferences. Where you select which pics and movies you want to store on your iPhone. That way, whatever the last thing you imported from your phone, into iPhoto, will have its own folder in your iPhone's photo library.
