I doubt wheather you have ever tested it by yourself?
The value will be changed and just initialled once.If ParticlesAreGlobal is ture(in most condition) AbsoluteTransformation.transformVect(array[i].pos);

When the code is invoked, the pos is changed.It will be chaged again when an now particle ...

add the code below into
s32 CParticlePointEmitter::emitt(u32 now, u32 timeSinceLastCall, SParticle*& outArray)

if (Time > everyWhatMillisecond)
{
Time = 0;
Particle.startTime = now;
Particle.vector = Direction;

// add here
Particle.pos.x= 0;
Particle.pos.y= 0;
Particle.pos.z= 0;
// OK ...
