Because italic, boldface and roman shape are not just text 
decorations when used in math it changes the meaning of the symbols:

Mathematical constants and explicitly defined functions (i.e., 
sin and cos) are printed in roman.
Variables, numbers (digits) and functions are printet in italic.
Vectors in bold italic etc.

This meaning does not change with the shape of the surrounding text.
