Understanding the function "Loop" in Regions Option

I do not understand this Funktion therefore I cannot translate it into german.

it says:
If there is only one item in this region should it loop?

all my tests Show Looping regions with 1 item without checking this box.

Have a look here please - Understanding Media Duration and how it affects the playback of a Layout

I believe it’s explained well there, if you’d have any follow up questions, please do ask here.
