I consider it just another approach.

Arthur Haddy, Decca studios chief technical director, has stated on numerous
occasions that the DECCA cutterhead could make Stereo vinyl disks either
45/45 or vertical/lateral at the flick of a switch.

The cutterhead stayed the same but the signals driving it was matrixed
differently to either produce 45/45 or vertical/lateral when switching said
switch.

So in the end they had no problems at all to agree to the 45/45 system as a
wordwide standard because of said switch.
