Quite right ;-) But this is not the point.
Make a small test: Use my simple project and export the model that Y is top and a second time export that -Y is top, both with Z to front. Import both stl files with standard settings. You will see that Y is allways on top. This cannot be right.
If you export Y or -Y as Up with other settings for forward, the Y side of the exported object is neither on top (again imported with default settings).
Or check the orientation of the exported files with the free online stl viewer https://www.viewstl.com/
There is a mismatch...
I mentioned the problem when exporting an object and importing it in a slicer (Cura 4.3). Wether I set Y as top or -Y as top direction there was no change in the result.
So I made the test object above, exported in all possible combinations of directions and imported all these back to blender. Ok, I did not see the possibility to change the orientation while importing so I always used the default settings: Z top, Y forward.
The result is in the STLTest1_xyz_uf.blend. Every imported model has the name of the orientation I exported it: e.g. -zu_xf (-z up, x forward).
Maybe there is also a error in the import routine because in the front view z is positiv pointing to the top, but y is negativ pointing to me of spectator. I will test this too....
