You function here needs a little work and it may fix your problem.

this.collide = function(){
  for(var z=0; z<this.positions.length-1; z++){
    for(var q=z+1; q<this.positions.length-1; q++){
      return this.positions[z][0] == this.positions[q][0] && this.positions[z][1] == this.positions[q][1];
    }
  }
}

2 things are wrong.

1. You are dropping out of the loop the first comparison. You will want to do something like if (something overlaps) return true then outside of both loops return false if you make it through successfully
2. You will want to make sure that the z segment != q segment or you will always have a collision

Looks cool. Lets see Mario next ;)
