Why do dependent triggers within the same node not work correctly in Zabbix?

Question

Zabbix

There are 2 nodes. Node1 and Node2. The availability of Node2 depends on Node1.
Ping triggers are hung on nodes. In order to avoid unnecessary notifications, the Node2 trigger has a dependency on the Node1 trigger. But if you specify the dependency in this way, then the dependent trigger does not change its state, which is quite logical. But I would like to see a clear indication of unavailability on the network map. For this, one more Ping trigger was added to each node, but with the status of informational. So that 2 triggers in Node1 and Node2 would not fire at the same time, informational triggers were specified to depend on the main trigger on which notifications are triggered.
And logically, if Node1 is unavailable, then the main trigger should not work on Node2, since it depends on the trigger in Node1, and the second trigger, which depends on the main one, should work. But for some reason it doesn't work either.
What am I wrong tell me?
