Yes, except in biological systems you can chart out long chains of consecutive electron exchanges such that you end up with electrons transferring between two molecules with the intermediate molecules remaining the same in the end. In my mind, this makes an analogy to electrical systems, for example a simple battery powered circuit more acceptable. Still agree that connecting it with 'current' is probably not the best approach.
