You are maybe confused. It is certainly possible, especially as the manual is not very clear here.
The section from the manual you quotes says "After a few seconds of inactivity, the algorithm led will turn off and space will revert to normal preset or play mode."
At this point, the last algorithm displayed will be loaded. You can confirm this by pressing the encoder again.
Your confusion may be caused by the fact that the original preset name is displayed once it returns to normal mode.
Note that you must save this preset if you want to keep the change.
