it is not the same… you have 8 recorder buffers, one for each track… so you can record something on one track and play it on another, which is useful…
anyway…

say you are using track 1
you double tap the track 1 button
you go to flex and hit the arrow key right -> and then go up and select flex recording buffer 1.
then your playback trig will play the recorded sound that you have recorded with your record trig.
