Stereo Outs AND left/right? or

I’m working with Cubase 5.5. In Audio Mixdown I check the stereo Outs for a stereo mix down of my tracks.
Then I check real time export, skip mono and split channels, and what’s this? L/R has been added as a choice. (mixdown left & right channels). Is this the same as a stereo mixdown? Do I need to check this? Thanks, David

I don’t recall ever seeing that, but maybe different versions have different options, but just try it and see for yourself what it does to a mixdown.
