It is the states beginning with ignorance that should be understood as dependent origination.  With ignorance as condition there are (volitional) formations; with formations as condition, consciousness; with consciousness as condition, mentality-materiality; with mentality-materiality as condition, the sixfold base; with the sixfold base as condition, contact; with contact as condition, feeling; with feeling as condition, craving; with craving as condition, clinging; with clinging as condition, becoming; with becoming as condition, birth; with birth as condition there is ageing-and-death, and sorrow, lamentation, pain, grief, and despair; thus there is the arising of this whole mass of suffering.  This is called the dependent origination.
It is the states beginning with ageing-and-death that should be understood as dependently-originated states.  Ageing-and-death is impermanent, bhikkhus, formed, dependently originated, subject to destruction, subject to fall, subject to fading away, subject to cessation.  Birth is impermanent... becoming... clinging... craving... feeling... contact... the sixfold base... mentality-materiality... consciousness.. formations... ignorance is impermanent, formed, dependently originated, subject to destruction, subject to fall, subject to fading away, subject to cessation.
The states that are conditions should be understood as the dependent origination.  The states generated by such and such conditions are dependently-originated states.
It should be understood that dependent origination has the characteristic of being the conditions for the states beginning with ageing-and-death.  Its function is to continue the process of suffering.  It is manifested as the wrong path.
