The "1" Res call variations search only ONE res file for your resource - the
currently active resource file.

The other calls (GetNamedResource, etc) search the entire resource chain, which
is typically something like <res file>-><application resource fork>-><system
file resource fork>.  So if the resource you want is not in the currently open
resource file, it will look in the application's resource fork.  If it's not
there, it will look in the System file's resource fork.  Sometimes this is what
you want, like when opening a dialog box (like the standard save/open dialogs)
or getting an icon.  But other times this is inappropriate behavior; hence the
"1" calls.
