So what's missing here is some historical background to Tapper, which could give some insight into why the patent was written this way.
Bally/Midway regularly contracted out to external design firms for game ideas. One of these firms was Marvin Glass and Associates, a toy design group in Chicago. MGA was responsible for many childhood favorites such as Mouse Trap, Simon^, Lite Brite, Operation, and many others.
The toy industry is highly secretive and extremely competitive. Anything and everything that comes out of their design labs is immediately put into a patent application. Tapper was no exception to this rule.
(^ Simon was designed by Ralph Baer, who was on MGA's payroll at the time. It can also be argued that, given the amount of copying that went on with Pong and other clones, Baer also made sure future video game designs within his view were more closely protected than before.)

It seems they could have caused quite a bit of carnage for later multi-player games if they had decided to enforce it.
The full filing has a bunch of similar flow charts, and a bonus 100+ page rom dump :)
[Insert legal stuff . . . they settled for a copy of the arcade machine. Being a housemate, I got to help move it every time we moved. Those things are heavy]
