If you'll look at soot.coffi.CFG, you'll see that every time Soot
encounters a PUTFIELD or a GETFIELD, it instantiates a new
InstanceFieldRef.  The Jimple parser does the same thing.

Since InstanceFieldRefs are mutable, it's probably not a good idea to
share InstanceFieldRefs between two different statements in code that you
generate, even if Soot uses Boxes.
