Quote - probably that you can think with your left brain..ie..you can think logical and rarionale when you wnat. ie..you do use two sides of your brain. :-)

A more likely explanation:
The Brain runs an internal check on sides. The Brain decides that neither side really works all that well. The Brain becomes confused and the 'rotation autoconfig' crashes. The Brain transfers rotation control to user input, as a workaround for the faulty autoconfig.
That was supposed to be fixed in Brain 1.1 update; but I guess I'll have to wait for Brain 2...
