It strikes me as weird, describing it as a parameter to the algorithm identifier - firstly, it seems this wording is derived from where you want to fit it into ASN.1, and secondly, why constrain it in this way? A protocol could easily transfer the random value somewhere other than in the algorithm identification. Indeed, if the protocol doesn't use algorithm identifiers every time it uses a hash (TLS would be an example of this, surely?), you'd be utterly screwed by this wording.
