Clarification to documentation

At what point do the variables NetworkServerEvent() and EventClient() get updated, after they are set? I believe it is after ReceiveNetworkData or ReceiveNetworkFile are called. This is important for those of us who use threads with sockets.
To handle this correctly, you must call ReceiveNetworkData or ReceiveNetworkFile prior to creating a thread to send a response. If you try to pass EventClient() to the thread to call ReceiveNetworkData or ReceiveNetworkFile, you will encounter some strange results.
Consider, if you will, the following code from the documentation, with two additional lines:

Select SEvent

MessageRequester("PureBasic - Server", "A new client has connected !", 0)
Case #PB_NetworkEvent_Data
MessageRequester("PureBasic - Server", "Client "+Str(ClientID)+" has send a packet !", 0)
ReceiveNetworkData(ClientID, *Buffer, 1000)
MessageRequester("Info", "String: "+PeekS(*Buffer), 0)
; updated documentation next line
MessageRequester("Info", "'NetworkServerEvent()' and 'EventClient()' have been updated", 0)

ReceiveNetworkFile(ClientID, "C:\TEST_Network.ftp3")

Case #PB_NetworkEvent_Disconnect
MessageRequester("PureBasic - Server", "Client "+Str(ClientID)+" has closed the connection...", 0)
