Usually the direction ratios and cosines are defined in a manner away from the origin. But yeah, you are correct, you can define them in either way and here it won't matter since, you will end up squaring everything and hence, it shouldn't matter. But still, to be on the safe side, always use OE instead of EO, unless and untill it is explicitly mentioned in the question.
