Or, if you think in terms of truth tables:
| original $a | original $b | $a ^ $b (gives new $a) | $a ^ $b (gives new $b) | $a ^ $b (gives new $a) |
| 0 | 0 | 0 | 0 | 0 |
| 0 | 1 | 1 | 0 | 1 |
| 1 | 0 | 1 | 1 | 0 |
| 1 | 1 | 0 | 1 | 1 |
As you can see, original $a is the same as new $b and original $b is the same as new $a.
