Playing for composer

Playing organ piece when the composer is present can be very disturbing. Is it really necessary? What purpose does it serve when the organist will never be able to reproduce the perfection that is vivid in composer's mind, even though he only heard it on MIDI? Does the organist enjoy it? She's probably sitting on the bench thinking while playing:

"I've mostly played music created by people who are long dead. That's what I like about them. They never complain. I wish this guy was dead too."
