Hi John,
Let' just say that this alt universe is a little ahead of us technologically.
The only ones that knew that the one in disguise was Superwoman were Mitzie and Frank Baxter and they will not be seeing Lois to match her up. Besides, in her hooker outfit she wore a red wig.
It was only when in the messenger outfit that she was addressed as Lois and that only in front of Izzie and Bill Henderson and they used the opportunity to build the secret by setting up the double date.
