   S05.   Decrement inner Hop Limit or TTL
   S06.   Submit the packet to the IPv6 module for transmission to S1

   After the H.Encaps behavior, P1 and P2 respectively look like:

P1 and P2 respectively dont look like that.  They are encapsulated.
These are new packets that are created.

   - (T, S1) (S3, S2, S1; SL=2) (A, B2)

   - (T, S1) (S3, S2, S1; SL=2) (A, B2) (B3, B2, B1; SL=1)

The P1 and P2 are indeed not modified, they are encapsulated. But there are new packets that are shown there: P1` and P2` if you wish.

After encapsulation one couldnt say that a packet looks like before.

An encapsulated packet does not know what's happening to itself, and has no idea about its encapsulating header.
