CC2530: Group assignment for Nodes

Can one Node device has multiple group ID assigned from same coordinator ?

My Set up -

NV_INIT and NV_RESTORE enabled in both the coordinator and Router (Node) device

cc2530 ZNP Coordinator

cc2530 Z Stack Lightning ( ZigBee Router )

and I know that when sending the data through AF for group address, the address Dest_Address-Mode is set as '1'

Now suppose there are 5 nodes listed in one group ID, the messages will reach the nodes on basis of Group ID or Node address ( Short address ) one by one to each five nodes sequentially ??

The message will reach the nodes on basis of Group ID.

Like there will be one message frame format for all nodes whoever belongs to the particular group ID

Can one node be assigned with multiple group ID's ?

Yes, one node can belong to multiple groups.

That means such particular nodes is able to receive different group configuration's data
for example -
Say Node 1 ios assigned with two group GID1 and GID2

Now some sent data for GID1 and then some other data for GID2

Node will receive both the data and I think if for same cluster ID and attributes the data is sent then it will retain the data for GID2 ( as this is sent recently )

Will the behaviour be like this ??
Correct me if I am wrong in understanding
