Looking at your pdf from right to left only the one on the far left is incorrect, the text should be 180 degrees. This is a standard and has been for the 30 plus years I have been in drafting. Text should always read from left to right or bottom to top unless it becomes more than 90 degrees as shown in your samples. A simple rule is that the text should never be upside down. If you were to write the text as shown on your sample from bottom to top the ones on the right would be upside down, therefore you switch the text to read from top to bottom. Just so you will know this location of text and orientation has been standard at least from the 1940's. I have a book showing the proper drafting techniques written in 1942.
