A distinction between the two is not being made, in fact they are together as the same which they are. This is not speaking of heavenly angels but angels in the sense of human messengers who come from other lands where different languages are spoken. Most people did not travel far or at all and only knew their own language but angels/messengers would come and often speak a different language.
The point is it doesn't matter what language you are speaking if you speak without charity.
