If one understands 'a part of an expression' and 'subexpression' as the
same thing, I would understand the last part of the second sentence to
be just another formulation of the last part of the first.

Maybe the documentation could be improved, so it doesn't use too many
Mathematica specific words which are not clearly defined...
