Of course they are. That was only an example of when it may be acceptable to refer to both of them as "coke" since they are so similar, just as "kleenex" can refer to any brand of facial tissue. It's a genericized trademark. The point was that other soft drinks are so different that they shouldn't be called "coke" to maintain clarity.
I guess it's a bad example, largely because of the stupid fanboyism and how Coke fans insist that Coke is totally superior to Pepsi and vice versa, when in reality they're damn near the same thing.
