0|01][100|0][1|011][10|0]
The first tile in the sequence has to have the same character on the "top" and "bottom" of its tile.
The only tile that fits this description is the tile [0|00], so we have to start with that one.
Our next tile has to begin with a zero in its top part, so we can only choose either [0|00] or [01|10].
We can't choose [0|00] since we would end up with [0|00][0|00], giving a 00 on top and 0000 on the bottom and there will be no possible next moves.
Thus, the next move must use [01|10], and we have the sequence [0|00][01|10], which is 001 on the top and 0010 on the bottom.
Again, because of the extra zero on the bottom, the next moves are limited to [0|00] and [01|10]. We can't pick [0|00] because then we would end up with [0|00][01|10][0|00], which is 0010 on the top and 001000 on the bottom, which has no possible next moves.
So, we have no choice but to go with [01|10], which nets us with [0|00][01|10][0|00][01|10], which is 001001 on the top and 00100010 on the bottom.
There is no way for the top halves of the tiles to "catch up": this is why there is no match for the tiles {[0|00],[11|0],[01|10]}.
