What's so particular about posting couplets at the gate?

Note on posting Spring Festival couplets:

Traditionally, the first couplet of Spring Festival couplets should be posted on the right hand side (that is, the left side of the door), and the second couplet should be posted on the left hand side (that is, the right side of the door), and the horizontal batch is also read from right to left. Upper and lower couplets cannot be posted backwards.
