There's always someone willing to do it wrong though eh?
As you said, you'd think that it would be a case of using common sense to run the tow mower to the left of the lead mower, but that's not always the case with operators.
I can see that in some cases where the grass is short and/or thin someone might run the tow mower to the rt of the leading mower to further chop up the clippings, but you'd really be setting yourself up for an accident when you start swapping sides with the mower being pulled.
Knowing where that tow mower is (without looking at it) has to become automatic, just as is the case with using any mower. If not, it's just a matter of time before you crash the tow mower into something, or worse, somebody.
