Well, it's pointless.

Turbulence in textures work backwards, so a turbulated texture can have
the same point turbulated to two or more locations. The vturbulence
function works forward and thus is incompatible with turbulence in
textures, and naturally a function can not return more than one result.

However, for very small amounts of turbulence, the results for forward
and backwards turbulence may be close enough that they won't be spotted
(because turbulence directions change gradually).
