This example from the Tactile graphics guidelines (Example 6-17) differs from the one in your first note because the labels in the 6-17 graphic are in UEB. The key list is rendered in the same code (UEB) which is why the Nemeth switch indicators are applied individually to the three labels. Keeping in mind that the items in a key are read as needed when the reader encounters them in the drawing, the transcription shown in Example 6-17 makes sense.
