How to get sync information with .Net API

I apologize if this question doesn't make sense or if I'm not posting in the correct location. I am a .Net developer and never even heard of F5 until I was tasked with developing a web interface for controlling our devices. From what I was told, we have a device group of two devices that are set up as a failover. I need to determine if the devices are in sync. I have the name of the device group and the names of both devices.

Determine if devices are in sync:

This code works, but I'm not sure it makes sense because I would expect to be connecting to the device group, not one of the devices. However, this is the only way I could find to get the sync state. This code returns iControl.ManagementDeviceGroupMemberState.MEMBER_STATE_IN_SYNC. The reason it doesn't make sense to me is because what if the device I'm connecting to is down and the other device is now the active one? In that case, I would not be able to connect, right?

Interfaces m_interfaces = new Interfaces();
m_interfaces.initialize("Device1Name", 443, userName, password);
dg.SyncStatus = m_interfaces.ManagementDeviceGroup.get_sync_status_overview().member_state;
