That's an easy enough question to answer. Lots of folks make star wars fan films - some low budget...some with larger budgets and green screening. He could easily have been videotaping himself for FX tests....you practice with a broomstick, then rotoscope the blade later in After Effects.
There's a whole section at the force.net devoted to this stuff. I've picked up several After Effects techniques there (rotoscoping, force lightning, holographs, compositing, etc.) as well as poor-man's filming techniques. They have a scifi3D forum which is pretty cool as well....mostly MAX modelers but some really top-notch work there.
Here's a link to the fan film section if you're curious:
