The main issue is if Queue refers to the logical vulkan queue the work is being submitted on. Or the actual hardware queue.

This is 100% the VkQueue object. The hardware implementation of how it maps the VkQueue is outside the scope of any Vulkan Tool

My main concern was this 1 line here from the description.

An application may open a debug label region in one command buffer and close it in another, or otherwise split debug label regions across multiple command buffers or multiple queue submissions.

Which makes it sounds like you can open a debug label region on 1 queue. Submit. Then end the debug label, then submit.

And when talking to @MarkY-LunarG (The author of this extension) they said

I was working with the AMD people who were using this, and we really can't validate it. I thought we added a note that we might not be able to validate it because of all this.

This logic goes back because we were asked to support this across multiple QueueSubmits. Because of this, we really can only validate this on the GPU using something akin to GPU AV where we have a check for every BeginLabel and increment a counter and then check every EndLabel on the GPU to make sure the value is > 0 before we decrement and throw the error then if the value is <= 0. It might just be something we can't test properly at this point. [NOTE: There are other valid usage statements that also fall into this bin].
