I don't know if it's correct, but i think it's not possible to get 2 strands parallel to each other because it is impossible to form hydrogen bonds between 2 same purines, or 2 same pyrimidines. imaging if you lay out the strands parallel to each other, one strand is going to be the mirror image of the other, so, they are going to repel each other.
