It's because it has a 3-second cooldown between targets so it can reload. It will "lock on" to a target, attack with its Glaives, then reload if it's out or if the enemy dies. It's probably because the Glaives do high damage and hone-in on multiple enemies, so if you let it shoot in rapid sucession, it might kill everything.
