I am afraid yes since it uses Vect_line_length(). Certainly this is
rather useless.

The doxygen documentation for that function suggests:
   "For Lat-Long use Vect_line_geodesic_length() instead."

The "easiest" way would be to manage things as done in v.distance.

Please open an enhancement report in trac for this.
