Again, it would be useful to clarify what you mean here. Referring to,
do you see r1 as a g-box? g-snap? g-text?

Quoting the graph concept terminology document,

There may exist a need to make statements about a g-snap,..., thus a way 
to refer to one may be required

There may exist a need to make statements about a "state" of a g-box, 
either previous or future, thus a way to refer to a g-snap as being the 
state of g-box-X at Y time may be needed.

It seems this is quite relevant to us.
