It's meant to be in favor of merge mining.
Dogecoin uses scrypt, which is a very popular algorithm. If any larg= e currency were to be attacked through merge mining, it would probably be l= itecoin miners attacking dogecoin. But if you control enough of the litecoi= n network to do attack mining against dogecoin, you almost certainly have a= huge vested interest in cryptocurrencies doing well. By attacking dogecoin= successfully, you'll cast doubt on the entire cryptocurrency ecosystem= and hurt yourself in the process.

The launch thread says it clear: "very scrypt, such random, much
profit, wow, many coin".
So it seems that Dogecoin doesn't use SHA256 like Bitcoin, but scrypt like most of the other scamcoins.
Anyway, I don't see anything in your comment in favor or against
merged mining...
