This is normal behaviour. \mathbf allows to use the text bold font in
maths, in other words it produces in maths the same output as does
\textbf in text; hence the upright result.
\boldsymbol, from the amsbsy package (deprecated in favour of bm), and
\bm, from the bm package, do something different: they select bold
maths fonts, provided these fonts are available. In other words they
take the (italic) math symbol you are asking for, look for a bold
version of it, and, if it's available, pick it up; if it's not, they
apparently revert to the non-bold version. Both \boldsymbol and \bm aim
at providing more practical and extensive variants of LaTeX's original
\boldmath.
