How do I - Loopindex - What is it good for?

From the manual

"loopindex

Get the index (number of repeats so far) in any currently running loop."

My question is... would someone explain this to me in layman's terms? - I understand that, you can use it to 'fix' wait loops as explained here

• https://www.scirra.com/tutorials/723/us ... t-in-loops - But I can't wrap my mind around other ways to use it, and I'm hoping I'm not making things more difficult for myself if I should use loopindex in some places.

I saw it referenced in this thread about infinite spawn enemies - viewtopic.php?f=147&t=151820&p=960011&hilit=Disable+group#p960011

And I was wondering what other ways could you apply this?
