Is AutoResetEvent really susceptible to dropping Set() calls?

[The docs](https://learn.microsoft.com/en-us/dotnet/api/system.threading.autoresetevent?view=net-7.0#remarks) for `AutoResetEvent` say:

> There is no guarantee that every call to the [Set](https://learn.microsoft.com/en-us/dotnet/api/system.threading.eventwaithandle.set?view=net-7.0) method will release a thread. If two calls are too close together, so that the second call occurs before a thread has been released, only one thread is released. It's as if the second call did not happen.

This reads to me as if the following scenario could happen:
* 2 threads are waiting on the event
* 2 calls to Set() are made in rapid succession
* Only one thread is released
This seems like a pretty major issue! **However, I'm wondering whether this bug is actually real and if so whether more information can be provided about it.** It could also be that I'm misinterpreting the scenario described in which case perhaps the docs could be clarified.

Some notes:

* I tried to reproduce this scenario on .NET 7 Windows and failed to do so. I used a program like this:
```
using var @event = new AutoResetEvent(false);
const int Threads = 100;
var b = new Barrier(Threads + 1);
var tasks = Enumerable.Range(0, Threads).Select(t => Task.Factory.StartNew(() => { b.SignalAndWait(); @event.WaitOne(); }, TaskCreationOptions.LongRunning)).ToArray();
b.SignalAndWait(); // wait for all threads to spin up
Thread.Sleep(3000); // give them time to start waiting on the event

for (var i = 0; i < Threads; ++i) { @event.Set(); } // call Set() in rapid succession
// making all the Set() calls from different threads also seems to work
//b = new Barrier(Threads);
//for (var i = 0; i < Threads; ++i) { Task.Factory.StartNew(() => { b.SignalAndWait(); @event.Set(); }, TaskCreationOptions.LongRunning); }

Console.WriteLine(Task.WaitAll(tasks, TimeSpan.FromSeconds(10))); // True only if each Set() released a thread
```
* `EventWaitHandle` (the parent class) does not mention this issue in [its docs](https://learn.microsoft.com/en-us/dotnet/api/system.threading.eventwaithandle?view=net-7.0#remarks) that I could find.
