Could you please define exactly what it is you want to get as an output and where you are to use that output?
If you just terminate the inner loop the outer loop will iterate and thus restart the inner loop. The inner loop has it's conditions set to stop but that just means that it will run just one iteration...so now the outer loop runs continously, making the inner loop run one iteration each time. In this case you'll get multiple values out of the outer loop since it is running multiple iterations. If all you wanted was one value, the one from the last iteration of the inner loop the first time it was called you'll need to terminate the outer loop at the same time as the inner by wiring the stop of the inner to the conditional terminal of the outer as well. In short - try to figure out what you want and make sure the logic of the code really fits that... By the way; the use a a sequence is not necessary. If you want to clear the array prior to running the loop just wire the error output of the property node to the left border of the outer while loop, that way data flow ensures the right order of execution and the code becomes easier to read (sequences is normally avoided where data flow can be used instead, data flow should be the primary controller of execution you use when writing G). The use of a property node for this task is not the best option either (in this case you could use an invoke node to reset the default value instead anyway) - use locals for this (locals too are to be avoided though - if wiring can do the job).
