I really wouldn't be looking in to it if I thought they would run through it. We're in a rural area and we routinely let the dogs out without any fence/tether when we're supervising. They stick around and don't wander off, we just want to keep them out of the neighbor's yard areas when we're inside and they aren't without having to tie them.
I was more interested in the practical implications, such as the collars being faulty/the transmitter not working properly, etc. But it sounds like no one has used them before. Lol
