1. inet:ipv4=1.1.1.1 is created and its path is initialized, but there are no runtime vars so it gets no path vars
2. the init is run, setting $global_count=0, before yielding the 1.1.1.1 node further
3. at the start of the loop, the node+path is cloned for each iteration, but at this point the path has no vars set yet
4. inside the loop $global_count is pulled from the runtime since each clone of the path does not have it set, this causes it to be incremented from 0 -> 1 -> 2 -> 3 in the 3 iterations
5. we reach the bottom of query and print $global_count which has a value of 3
6. inet:ipv4=1.1.1.1 is created and its path is initialized, there are now runtime vars set so $global_count is set to 3 on the path from the value on the runtime
7. the init has already been run so nothing happens and the 2.2.2.2 continues on
8. at the start of the loop, this time we do have path vars, so each clone of the path has $global_count set to 3
9. inside the loop, $global_count is now pulled from the path rather than the runtime, so each iteration of the loop only increments the value from 3 -> 4
10. we reach the bottom of query and print $global_count which has a value of 4
