You are completely wrong mate. Sorry.
"Soft" means less detail, objects look more rounded, that's why the icon.
"Strong" means more detail, more "aggressive" edges to the objects.
This nomenclature is used in all the cameras i know, if you don't understand the logic behind this you better start getting used to it.

The icons are well placed, despite not being the clearest.
I'm not using the FW1.4 but in my FW version the icons are correct, however, i would change them for something more meaningful (because people get confused).
Normal icon would be a zero (0), strong icon would be a (+) and soft a (-). Simplier, uglier maybe, but easier to understand.
I think your confussion starts because you believe SOFT is a better looking image, but technically speaking, in camera language, SOFT is less detail. That's what RAW format in photography gives, less sharpness, less contrast, less color to give more room in post.
