You can get burned coffee because the same container you use to heat the water to make the steam also holds the coffee and that still heats up. If you start with cold water that's more time for the coffee grinds to heat up and if you don't take it off the stove when it's done and cool it down right away that's time for the brewed coffee to start to burn as it's sitting in a heated hot pot.

Most other methods don't have you heat the coffee and the water together so you can only really burn it if you put it on a heating element after.

James Hoffmann [1] and many others recommend starting with really hot water at the bottom, so the coffee grinds have less time to heat up.
