No, the right hand valve in that picture blocks vacuum retard to the vacuum retard side of the diaphram pot on the distributer. There are no electrical solenoid valves in the vac advance line.
There is a little mechanical thermal valve in the vacuum advance line on the late eightee's USA cars. It's mounted back on the breather cover with red cloth covered hoses going to it.
It blocks vacuum advance for a while until engine heat opens it after a cold start to lower emissions while the catalytic converter is heating up.
I'm sure they all work perfectly after 25 years... right.

This has been discussed in other threads before.
