One doubt regarding TTL processing in label stack!

IP TTL value ie copied to the Label1 TTL field in the shim header. Now
suppose another label is pushed by an LSR. Will the Label1 TTL value
be now copied to the Label2 TTL field (which is not the top label)?
And the reverse will be done when the label2 will be popped?

regards,
Shilpa
