I have no disagreement with this statement.It's not all about cell voltage, it's also about the internal resistance of the battery. This internal resistance increases as the battery ages. So when you ask the battery for high output, the older battery will have a higher internal resistance, so it contributes less when paired to a better battery with less usage cycles on it.
Not helping is not the same as hindering. I'm saying what you said above. You may not get peak performance, but you'll get somewhere between the best battery's performance and 2x that depending on how much the worse battery can supply.A battery doesn't have to be "shot" to lag behind and drag down and hinder the performance of a good battery.
It's still not going to be /less/ than the best battery by itself, without a shorted cell.
