The bills in my wallet are all the same. Looking at the portrait side and rotated 90 degrees clockwise, I see "USA TWENTY" right side up, then the same text upside down, then repeating. I would be worried if I saw the same thing with a bill rotated 90 degrees the other way.
This is described on the BEP site at https://www.uscurrency.gov/denominations/20. Click the "A" on the left side of the bill to read about the security thread: "Hold the note to light to see an embedded thread running vertically to the left of the portrait. The thread is imprinted with the text USA TWENTY and a small flag in an alternating pattern and is visible from both sides of the note. The thread glows green when illuminated by ultraviolet light."
