2 X 200 amp panels with one IotaWatt and one VT

I have a 400 amp service feeding two 200 amp panels installed side by side. Looking to monitor mains on both panels and some of the larger circuits they feed with a single IotaWatt.

Can a single VT accurately reference voltage for both 200 amp panels when plugged into a circuit terminated on only one of the panels?

Thanks!

Yes, that will work fine.
