Actually, I can't see exactly where such lines were cut. Anyway, I must say that I've never even seen a Mazda compressor with two separate fittings; and on my 1988, the two short metal lines that attach to the compressor have rubber lines crimped onto them like in that diagram you posted above (#12 and #13). You can see the single attachment bolt and the rubber crimped lines in my photos posted earlier.
As to your question about the pressure switches: damn sure that my 1988 has only one switch, and it screws into the drier, not in the line. Both of those switches shown in your diagram are in the same line - just separated by the drier - and prevent compressor from engaging and doing damage if the refrigerant pressure is too low, don't know why one would need two of those?. And the de-icer/freeze sensing thermostat switch mounts on the outside of the evaporator box #7, and has its sensing tube entering that through a small hole so it's in the air flow.
