Is it wrong of me to expect the following code to do the same thing with resetBoth set to true or false?

(processing 2.0.1)

PShape test;
PMatrix3D pm;
boolean resetBoth = false;
boolean shapeForVerts = true;

void setup() {
  size(400,400,P3D);
  frameRate(1);
  ortho();
  test = createShape(BOX, 100,100,100);
  noStroke();
  pm = doTx(test);
  if(shapeForVerts) shape(test);
}

void mouseClicked() {
  if(resetBoth) pm.reset();
  pm.apply(doTx(test));
  if(shapeForVerts) shape(test);
}

PMatrix3D doTx(PShape in) {
  if(resetBoth) in.resetMatrix();
  PVector tx = new PVector(
    random(-25,25),random(-25,25),random(-25,25));
  PVector rx = new PVector(
    random(-1,1),random(-1,1),random(-1,1));
  PMatrix3D ret = new PMatrix3D();
  tx.mult(-1);
  ret.translate(tx.x, tx.y, tx.z);
  ret.rotateX(rx.x);
  ret.rotateY(rx.y);
  ret.rotateZ(rx.z);
  tx.mult(-1);
  ret.translate(tx.x, tx.y, tx.z);
  in.applyMatrix(ret);
  return ret;
}

void draw() {
  background(204);
  translate(width*.5, height*.5);
//  shape(test);
  
  hint(DISABLE_DEPTH_TEST);
  fill(255,0,0); 
  pushMatrix();
  applyMatrix(pm);
  
  pushStyle();
  stroke(0);
  fill(255);
  box(100,100,100);
  popStyle();
  
  for(int a=0; a<8; a++) {
    pushMatrix();
    PVector cur = test.getVertex(a);
    translate(cur.x, cur.y, cur.z);
    sphere(10);
    popMatrix();
  }
  popMatrix();
  
  PVector pv = test.getVertex(0).get();
  pm.mult(pv, pv);
  fill(0,0,255);
  pushMatrix();
  translate(pv.x, pv.y, pv.z);
  sphere(5);
  popMatrix();
  hint(ENABLE_DEPTH_TEST);
}
