Yes...it does

There are two types of outlets, three prong and four prong. Both have
a white wire connected to one of the prongs, but only one of them has
a neutral. On a three prong, the white is the other hot (black=hot1,
white=hot2, bare/green=ground). On a four prong, black and red are
hots, white is neutral, and bare/green is ground.

If you have a black/red/white four-prong, you can use either
black/white or red/white, plus ground, to safely power a 120v outlet.
