No, you don't get it. The subject (man) has no existence
in its own right, for Heidegger until there is a conceptualization/differentiation of subject-object via language.
The overview is perhaps similar to a Buddhist holistic position involving ineffability. Language is like a 'field' in physics. It is the dynamic 'reality' in which a contemplative Dasein can exist as an operative agent contemplating 'self' and 'objects'. 'Selves' like 'things' are evoked
via language not statically represented by it.
Merleau-Ponty employed Heideggerian thinking in the study of brain injured war veterans. For example, he accounted for a soldier unable to 'salute' when asked, yet who saluted automatically when an officer appeared, in terms of the loss the ability to 'contemplate objects' via language. Heidegger argued that automatic, non-contemplative coping behavior (Gestalt assimilation-accommodation) was the norm for most human activities.
