Is the photo of the actual crankset? If so, then I don't believe it is the short spindle version. Two reasons why:
1) The inner chainrings in the photo is offset inboard of the bottom of the spindle - on short spindle cranks, the inner chainring is offset outboard of the bottom of the spindle.
2) The crankset has a removable spider, and I believe all SRAM removable spindle BB30 cranks use long spindles.
In any case, the easiest way to tell the difference is to measure the spindle. A short BB30 spindle is about 87mm long, whereas a long BB30 spindle is about 105mm long.
A short spindle BB30 crankset can only be fit to a 68mm threaded BB shell if the BB shell uses T47 threads. A BSA threaded shell is too small in diameter to fit bearings around a 30mm spindle inside the shell, and a short BB30 spindle requires too narrow a bearing stance to be able to use external bearings.
A long spindle BB30 crankset can use a wider bearing stance, so it can be fit to BSA shell with an external bearing bottom bracket.
