Application of Hard and Soft Waxes

I read on one website that there is a difference between the application methods of Hard Wax and Soft Wax.

Hard Wax - applied in the OPPOSITE direction of hair growth, and removed in the same direction of hair growth.

Soft Wax - applied in the same direction of hair growth, and removed in the opposite direction of hair growth.

Could someone please confirm this.

Thanks.
