Not only what @setr answered but consider also that by having a consistent ruling you can actually design or alter the order of triggers just by naming them according to a specific scheme. It just makes easier to understand what happens when triggers are invoked, without having to actually force specific cases by direct experimentation. I did not even know that the standard prescribed a FIFO order, looks like a pretty bad idea to me, actually.
