Hard to know for sure, but I took a close look at the inflator and it looks perfectly symetric, I highly doubt inverting it makes a difference in the way it deploys.
On the plus side, the advanatage in the way I installed it is that at no time did I have to disconnect the airbag (other than the ground), that's why I didn't feel I needed to disconnect the car battery. Once the cover was separated form the inflator, I simply reattached it to the new cover.
I should note though, that the eBay unit seems to be slighly lighter in color than the original cover, not so you'd notice in most lighting conditions, but more obvious in direct sunlght. Wonder if you noticed the same thing.
