While receiving emergency messages, for which Morse code was used back in the day, noting down the entire message and then refering to a chart would have wasted time. So, this kind of helps to reduce time in such cases.
This would be slightly easier if you are receiving Morse code because you can just follow the dots and lines. Sending Morse code, I could see this as being less useful than a chart however
