Nest power connector for 2 thermostats?

I purchased 2 nest thermostats for my heating only system.  I have a millivolt heating system.  

I installed the first thermostat and installed the nest power connector and step down transformer to get the 24 volts to the connector.

The nest thermostat I installed now runs correctly with no errors.  Question I have is can I run the other thermostat with the transformer and power connector I already installed or will I have to purchase another power connector?  The heating system I have has two separate zone controllers for the 2 zones I have.

I have the same question. The installation video looks like you can hook multiple thermostats up to the same power connector, but I spoke with a Google Nest specialist who said that you need separate power connectors for each thermostat.
