Yes, it is initialized, because OnlineSessionInterface.IsValid() is true, and *(OnlineSubsystem->GetSubsystemName().ToString()) is “EOS”.

There is the following code in the constructor.

	IOnlineSubsystem* OnlineSubsystem = IOnlineSubsystem::Get();
	if (OnlineSubsystem == nullptr)
	{
		return;
	}

	OnlineSessionInterface = OnlineSubsystem->GetSessionInterface();
	if (OnlineSessionInterface.IsValid())
	{
		if (GEngine)
		{
			GEngine->AddOnScreenDebugMessage(
				-1,
				15.f,
				FColor::Blue,
				FString::Printf(TEXT("Found subsystem %s"), *(OnlineSubsystem->GetSubsystemName().ToString()))
			);
		}
	}
	else
	{
		if (GEngine)
		{
			GEngine->AddOnScreenDebugMessage(
				-1,
				15.f,
				FColor::Red,
				FString(TEXT("Failed to get session interface!"))
			);
		}
	}

It did print Found subsystem EOS.
