I think that the system is like this:

_WIN32_WINDOWS is defined only for Win95/98/Me (the crappy ones)
_WIN32_WINNT is defined only for Win NT4/2k/XP/Vista/... (the OK ones)

WINVER is defined for all Windows, and equals _WIN32_* for any given OS.

Now, the above condition does have to use an ||, as it's never the case 
that both are defined. It's also true that it could simply be (in this case)

#if (WINVER >= 0x0410)

because there is no _WIN32_WINNT between 0x0410 and 0x0500..

You also made a slight mistake - the condition doesn't hold for neither 
of NT4 or Win95, so it's actually not that confusing :)
