Not necessarily. The level of technology that we're envisaging should be 
easily capable of recreating a brain from the recorded information. Not 
that I see that as being a very good option. There will surely be better 
physical systems that could serve to embody an upload. I'm thinking 
along the lines of utility fog brains and bodies, but there will be 
other options too, I'd think.

In fact, it might be very difficult to 'download' an upload into their 
original biological brain, and possibly impossible, as you'd have to 
convert all the upload's experiences as an upload into the biological 
equivalent, and the original brain might not be capable of holding those 
experiences without being changed a lot. It could well be that shortly 
after being uploaded, people would change so much that downloading again 
would be impractical, and creating a new, synthetic brain/body would be 
the only practical solution.
