A bug compounded with rotated line gradients, arrows, and appearances
There are some conditions for reproduction.
・ Line with arrow
・ Set gradation to line color
Two or more lines created by the appearance
It is good to change the line width or move by "deformation" to check the change of the overlapped line.
Rotate the object.
Then click on the eye icon in the appearance panel to show or hide each line. The direction of the gradation of the line not touching should change one after another.
I have confirmed this phenomenon in all versions from CS6 to 2020.
A similar phenomenon was obtained with the vertical axis reflect. In my tests it didn't happen with horizontal reflect.
I am happy to share that we have fixed this bug in our latest release – 25.2.3 which is available worldwide now.
Going forward, our goal is to fix as many top User-Voice bugs as possible and as frequently as possible. Given the nature of the fixes, some of the bugs will take a longer time to fix, but we are on it.

Thank you for all the feedback. Keep it coming!

Sorry for my previous answer. Seeing the demo makes a big difference. Yes it is defiantly a bug/limitation.
When rotating a stroke with multiple gradient strokes if no stroke is selected in the appearance only the gradient on the bottom stroke is rotated with the shape. If you select another stroke in the appearance stack, then that stroke will rotate with the selection, but as you say it will only rotate one stroke when the shape is rotated (if no stroke is selected in the appearance pannel or multiple objects are selected it will rotate the bottom stroke, in each object). This problem also persists grouping several of these strokes. Expanding line to shape does not help either. Only killing the shape by expanding appearance allows the line to rotate with multiple gradient strokes to rotate all the strokes.
I recorded demo.
Thanks for your comment.
But how do you explain that when you hide a line on the Appearance panel, the gradient direction of the other lines is reversed?

(After further testing after seeing the video I understand this comment was wrong)
I suspect it is not an error, it is dependant if the object or the path is selected. switch to the Selection arrow to make sure the objects are selected before rotating. If you only rotate the path the gradients will not follow.
