It gives you alternative trans possibilities. The middle pin can either be in the center-middle or the center-rear pads.

So what's the difference?

None at all. Just means it will accolade trans with different pin outs.

If you google 'OC44 pinout' you'll get images showing you the pinout, there should be a coloured (maybe red?) dot nearest to collector. From there pinout is C-B-E.
Depending which pcb layout you are working with identify which wire goes where.

Probably not worth it for casual solderers, but things like this are when I drag out my Peak DCA-55 :)

Although I think there are several ebay items now that do the same thing -- insert the component into the ZIF socket (pin order doesn't matter), press the button, and the screen tells you all about the component, and what pin does what.

I have the Peak DCA75.  It's great for casual screening, but I find it does tend to report higher gains than the RG. Keen method, FWIW.
