You're not understanding what I'm saying. Your premise is incorrect. Getting an eUpgrade isn't the same as buying a business class ticket when it comes to things like baggage allowance. See below from the AC eUp site (emphasis mine).
Although you will be seated in either Premium Economy or Business Class when your upgrade is confirmed, your booking will remain subject to the fare rules and restrictions of the booking class and fare option you originally purchased. These rules include, but are not limited to, mileage accumulation, change and cancellation fees, access to airport lounges and baggage allowance.
