I've notice the same in my network. I think it is due to the broadcast dhcp packets entering your trusted upstream server interface, originated in others switches belonging to the same vlan and without dhcp snooping enabled. This fact makes dhcp packets being broadcasted to every port and thus reaching other switches. I think if you configure dhcp snooping for your vlan in every swtich, with only upstream interfaces as trusted, you shouldn't see misdirected dropped packets anymore. I hope to test this in a few days.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
