The target appears to be the authoritative servers for the domain in question, yes?

The attacker may consider it more effective because it provides a degree of obfuscation, or maybe he has some reason to game the operators of the authoritative servers in question into denying requests from your recursors.

Most (not all) attackers don't know that much about TCP/IP, DNS, et. al, and they tend to copycat one another and do the same things due to magical thinking.
