No, it's not needed.  The current way to do FSAA requires both a 
kQ3AntiAliasModeMaskFullScreen style, and using 
kQ3DrawContextPropertyGLPixelFormat to provide a pixel format that 
supports multisampling.  The Cocoa example program illustrates this.  I 
guess we don't have a Carbon sample that does it, but it's pretty much 
the same.
