Purpose of this counter?

I'm jut having a read of the internals to get a better understanding of how the mod works and using it in my own mod development. I came across this odd code here. What is the purpose of this counter? This always returns true which removes it from the tasklist on the first run effectively making it a one-shot. Should this be <= instead? And why 30 times?

Oh yes you found a coding bug. I will fix it.

Thanks.

It used to be to handle the case where the other side chunk loading is delayed.
