Reason for uniform spacing of molex connectors?

I notice that the distance between the molex 4-pin hd power connectors on a given line from the PSU seems to be uniform, and seems to be very similar even on different PSU's from different manuf's from different eras. Is there a specific reason for this?
 
Consider that for most users the connectors will be going to two places; the 5.25" bays and the 3.5" bays. Notice how for nearly all power supplies there are at least two molex cables, on for each.

If you then put two devices next to each other which both require molex connectors and plug them both in from neighbouring connectors, you will find that it is snug, but you can just about bend the cable round to get it plugged in.

The length therefore is just long enough to have two devices right next to each other powered from the same connectors but not so long as to cause clutter and extra cost. You have at least two cables, one for each of the two areas where Molex devices are generally found, so there is no need for a very long cable to reach devices at both the top and bottom of the case

So there's no electronics-related reason per se that you're aware of?
