They were talking about breeding a Rainbow with this combination not a Rainbow with another dragon.

That combo produced a Sonic because Butterfly has the Air and Lightning elements. The elements creating the new dragon don't always come from both parent dragons. They can come from just one of the parents. Think of it as putting all the elements in a hat, shaking it up and pulling some out. What you pull out is the new dragon. The only exception is a same dragon pairing. A pair of Dodos, for example, won't produce a Sandstorm.
