That just remembers (in 'previous') and restores the currently
validated object while (in 'object') recursively walking through the
graph (which is a tree in 99% of the cases).

(seen includes: anObject)
ifTrue: [ ^ self ].
anObject isNil
ifFalse: [ seen add: anObject ].
That part just tries to avoid to go into recursion if a described
object refers to another object that descriptions refer back to the
original object. That was requested at some point in the past, but I
never dependent on that myself.
