In the original press release from January 1984 one could read that the

Macintosh, along with three powerful new Lisa 2 computers, forms the basis of the Apple 32 SuperMicro family of computers. All systems in the family run Macintosh software.

and that

“We believe that Lisa Technology represents the future direction of all personal computers,” said Steven P. Jobs, Chairman of the Board of Apple. “Macintosh makes this technology available for the first time to a broad audience–at a price and size unavailable from any other manufacturer. By virtue of the large amount of software written for them, the Apple II and the IBM PC became the personal-computer industry’s first two standards. We expect Macintosh to become the third industry standard.”

This was a marketing attempt Apple made to capitalize on the distinction between the old 8 and 16 bit and the newer and more powerful 32 bit microcomputers and at the same time a way to present the Mac and the Lisa together to help a bit with the (poor) sales of its first computer with a GUI.

The “Apple 32 SuperMicros” monicker was actually used internally at Apple since November 1983 and then used in some of the promotional material the following year, grouping the Mac with three Lisa configurations (without an external hard drive, and with a 5 MB or 10 MB ProFile drive).
