The trick for looping flows is that you should move it away from the first event (where any of the birth operators are), because you can not connect it back to that first event.
In the case of your screenshot, I guess you can you can keep the Birth, position objects and shape operator, then just use send operator to send them all into the next event... do you magic there... test it.. send it to another event... and in that (now third) event, you can also test it, and send it back to the second event.
Hope it's clear.. just move particles from first event, then make loops however you want.
