Good point. It is my experience with both of my teenage kids, diagnosed with adhd.
In general, it needs to be broad since it is difficult to predict if you get enough attention or not.
So starting with a very short explanation helps increasing the odds of that it will be processed.
Obviously you need to gauge whether your child is engaged in what you're saying. Maybe you have some experience that leads you to believe this, but I would encourage you to stop speaking for all neuroatypical people. Your experience is limited.
My personal experience with ADHD is that my focus latches on to certain things, which may not be the thing I want them to latch on to, or the thing that is most urgent to focus on. But often a conversation, particularly a conflict, is the thing my focus latches on to most readily.
