Edit: To ask what may appear to be a daft question... How will we know if the system treats our accounts as alternative accounts or seperate accounts? Is there anyway of knowing this?

You won't "know" as such in the future. The system has already detected you as an alt because you both registered from the same internet connection, so you know this now
Thus, even if you use another connection to play, you will always remain alts. The account registered first will be a "main" account, the one second (and more in the future) will be alts. The alt will not receive the first $5 credits in the MD shop as well.
