Ok, I now see where the confusion lies. I agree with the whole statement except that the augmented 6 chord sounds anything like the dominant 7 chord. The texture is the same in the chord, because of the clashing notes. 1 and b7 in the dominant, and #5 and 6 in the augmented. Both containing the same root and 3rd, but the augmented sound (#5) is still easy to catch. Maybe just for me, but it is. I can see where it can be confused with a untrained ear.

The Augmented 6 chords is found natural in both the harmonic and melodic minor keys.
