This quote doesn't really add up to me. It starts with people can't tell the difference and then goes on to say that half the people prefer Coke and half Pepsi in a blind taste test.
That implies to me that everyone can tell the difference and half of them prefer Coke.
Giving people both and asking which one they like better does not test whether or not they taste different.
A better method would be to prepare three random samples two of one and one of the other and ask people if they can identify the one that is different.
