Hi Julien, The StateSet::set*AttributeAndModes(...) and there for convenience, so one doesn't have to remember which GL modes are associated with the attribute being set and to ensure that one line of code is enough to set things correctly rather then multiple lines.
However, in modern OpenGL where you use uniforms and shaders far more than old fixed function style StateAttribute the GL modes part takes a back seat and is something that will be used far less.
