The only difference I have seen between the nazi swastika and the Hindu one is that the nazi one is at an angle.
Imho this has more to do with a lack of knowledge among the general (western) populations which mostly only know the symbol from the Nazis. But not all swastika are same as there are quite a few differences in orientation and details between the Nazi Swastika and the actual Hindu/Buddhist symbols.
