Just a guess, but typical modems had 2 jacks, one to connect to the
phone line outlet, and the other to connect a phone. So everything
would connect to a single phone outlet, and you wouldn't lose your
ability to have a phone by plugging the modem in. (The phone would be
disabled during periods when the modem was active.) This would only
work for single-line phones (not enough phone showing in that pic to
tell if it's single or multi-line).
