tbh, i've stared at thsi a bunch, and i have no feeling on what's happening here or why the new code is more correct. Can you write a non-brief explanation of what this class is trying to accomplish, how tehse two fields play into it, and why the new approach is 'correct'?

I don't understand this class well enough to detail its intended functionality. An explanation of the race condition is here:
The sequencing is complex enough that it required a handwritten derivation before I was able to construct a deterministic failure using 4 counters and 6 instances of ManualResetEventSlim.
