It is very strange and wrong, because alternating != inverting.
Making -9V out of +9V would be inverting, making "AC" from "DC" is
chopping (along with the chopper circuit, chopper transformer...).
Inverting is making something, well, inside out, upside down and the like. 
That's not appropriate for AC to DC.

But this is a cultural thing. Like other terms, e.g. "shipping" although 
most of the time there is no ship involved.
