If I recall, Bao-Dur was supposed to sacrifice himself to save the Exile right before crash landing on Malachor V. Hence why his remote is carrying out his orders instead of himself - it's his last will and testament so to speak.
I'd give you a source, but I think I read this in 2006. I simply can't recall what my source is. I can't even recall what the circumstances of his sacrifice were. I know it was never voiced or implemented, hence why no variant of it was created for a restoration mod. Sorry I can't be of more help.
