5.1 side LR vs Rear LR?

[kuchikirukia]

The Opus encoder just complained that my source was using Side LR and it changed it to Rear LR. QAAC kept it the same. Is this Bluray's DTS-MA weird for using Side LR? Is there any difference on playback?

In a 5.1 source both channels config (FL,FR,FC,LF,BL,BR and FL,FR,FC,LF,SL,SR) are equivalents without difference on playback.
