Would they be twins?

If a man gets two different women pregnant and they give birth at the sane time, are the kids technically twins?

I asked this because I remember a story of a woman who was pregnant with two kids, where it was almost certain that they did not have the same father. The news always said she was pregnant with twins, so I decided to flip the gender of the parent, in this case one guy, two women.
