Yes, I think that's why this type of dukkha is associated with neutral feeling. Because our existence and experience is conditioned and uncertain, neutral feeling will inevitably "tip over", either into pleasant feeling ( cue the suffering of change ie loss of pleasant feeling ) or into unpleasant feeling ( cue the "ordinary" suffering of pain ).
I think Sankhara-Dukkhata is of wider significance than this, although you are undoubtedly correct to say that it refers to neutral feelings and to point out that such feelings pass away and become something which frequently is worse. But if that is all it is, then it could be considered as a form of Viparinama-Dukkhata. Stuff changes, we can't rely on it not hurting us. Existentially, there is a wider problem than the hedonic tone of our experiences, and this is captured in the "wrongness" of our being conditioned entities. Sankharas "put us together", so to speak, and reconstitute our existence as apparently separate beings with insatiable appetites. Ajahn Sucitto is very good on this aspect of Dhamma, and the audio link given by Mike above is well worth spending 50 minutes on.
