A Low level question on UObject::BeginDestroy()

In https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Source/Runtime/CoreUObject/Private/UObject/Obj.cpp#L535, I as wondering why the object being destroyed was renamed to None before any sanity check. If there is an error, the sanity check below returns “Trying to call UObject::BeginDestroy from outside of UObject::ConditionalBeginDestroy on object None. Please fix up the calling code.”, which it a bit confusing. Any thought ?

void UObject::BeginDestroy()
{
	LowLevelRename(NAME_None);

	// Remove from linker's export table.
	SetLinker( NULL, INDEX_NONE );

	// Sanity assertion to ensure ConditionalBeginDestroy is the only code calling us.
	if( !HasAnyFlags(RF_BeginDestroyed) )
	{
		UE_LOG(LogObj, Fatal,
			TEXT("Trying to call UObject::BeginDestroy from outside of UObject::ConditionalBeginDestroy on object %s. Please fix up the calling code."),
			*GetName()
			);
	}

It most certainly seems so that the Log message was intended to show the original name of the UObject. Therefore it follows that the calls to LowLevelRename and SetLinker should come after the sanity check.
