A man wearing no shirt is lifting a shovel by a wheelbarrow as he works outside.
A woman wearing a snowsuit is skiing.
These are 2 completely separate thoughts.  Sentence 1 references a man with no shirt working outside.  Sentence 2 is a woman wearing a snowsuit while skiing.  The only similarity is that they are both outside.
The subject can either be a man wearing no shirt or a woman wearing a snowsuit, but cannot be both simultaneously.
A man and woman belong to different genders.
