fbx exporter question - 90 degree rotation setting

I notice that the fbx exporter applies a 90 degree global rotation in the X plane selected by default. Is there any special reason to apply such a rotation, since it is selected by default.

Some 3d programs use the Z axis as ‘Up’, some use the Y axis as ‘Up’, this 90 degree rotation fixes this difference. Select/deselect it depending on the application you are going to use the fbx in.

Much Obliged, Thanks.
