reflectors and positioning

[Johnny Reefer]

Is it just me?
Am I the only one not quite gettin' it?
What's the deal with J & L (I assume it's them and not the manufacturer, as no manufacturer name was provided) sayin' that this reflector gets mounted this way and that reflector gets mounted that way?
I read most of the AA article newguy provided. Pretty heavy stuff. I didn't get all of it, but I didn't see in there anything about mounting reflectors perpendicular this and parallel that.
It's not how you mount it, but the design of the reflector itself, right?
In this case, either a parallel reflector or a perpendicular one.
Both get mounted the same way, no?
That being the reflector facing down, toward the water surface, no?
And your light rays will be either of the parallel reflected type or the perpendicular reflected type, depending on which type of reflector you have, correct?

No....?

Cheers,
