Replication, delivery of variables simultaneously or not

Development Programming & Scripting

If I have two (or more) variables for the replication, may I be sure that they are delivered simultaneously?

Example:
There is a quite massive array MyArray.
There is a quite light bool variable bMyBool.
I change both of them on the Server in the one function and wait for replication:

void UMyClass::OnRep_MyBoolReplicated()
{
	GetMyArray();
}

void UMyClass::GetLifetimeReplicatedProps(TArray<FLifetimeProperty>& OutLifetimeProps) const
{
    	Super::GetLifetimeReplicatedProps(OutLifetimeProps);
    
    	DOREPLIFETIME_CONDITION(UMyClass, MyArray, COND_OwnerOnly);
    	DOREPLIFETIME_CONDITION(UMyClass, bMyBool, COND_OwnerOnly);
}

May I be sure, that GetMyArray() will turn back new (replicated) MyArray?
Or bMyBool can be replicated first?

My tests showed simultaneous delivery for both variables.
However, I still not sure that it works for 100%.
