Default 2009 WRX Rear Diff Fluid - Amsoil 75W-90 Gear Lube?

I had used Amsoil 75W-90 Gear oil in my girl friends 2009 WRX Transmission and I still have a bunch left over. Is this fluid ok to use in her rear differential also? I searched a bit and I am 99.9% confident that it is ok to use but I just wanted to confirm before I go putting it in and causing an issue.

Here is the stuff I have.

Synthetic Manual Transmission and Transaxle
Gear Lube 75W-90 API GL-4 (MTG)
Formulated specifically for demanding manual transmission and transaxle applications
