I believe they are talking about some manufacturers (read: sigma) tendency of putting "Macro" in the name of a lens that doesnt do 1:1 like a dedicated macro lens does. So then the question becomes, when is it macro? Could Pentax call the DA 16-45 "DA 16-45 f4 Macro" ? if there is no definition of what is macro then everything could be called macro. A lot of compact digital cameras have macro modes of varying magification. If thats macro then what is 1:1? some people call that true macro, to distinguish between that and all the other macro lenses out there.
lastly I must give you a nod as a fellow member of the Voigtlander society

Just be happy you have the most kickass macro there is

Note that Voigtlander has a 180mm lens that Sigma would probably call "macro" but Voigtlander more correctly calls it "close-focus" since it doesnt do 1:1 like the 125 SL does.
