vm.stats.vm.v_wire_count higher than vm.max_wired?

On a FreeBSD 12.1-RELEASE-p10 GENERIC amd64 system

vm.max_wired: 21669114
vm.stats.vm.v_wire_count: 39372890

Why does the wire_count go above max_wired?
 
Code: 
sysctl -d vm | grep -i wire
vm.max_user_wired: system-wide limit to user-wired page count
vm.stats.vm.v_user_wire_count: User-wired virtual memory
vm.stats.vm.v_wire_count: Wired pages
 
Thanks for the replies. However, on my system, there is no max_user_wired or user_wire_count:
Code: 
# sysctl -d vm | grep -i wire
vm.max_wired: System-wide limit to wired page count
vm.stats.vm.v_wire_count: Wired pages
If fact I found the above limits by doing
Code: 
# sysctl -a | grep -i wire
vm.max_wired: 21669114
vm.stats.vm.v_wire_count: 39372890
