No, the syntax is correct. What you're running into is the fact that the search engine is indexing the entire bib record, including item records, and the search itself is searching bibs, not items. Consequently, since the bib record in question meets both conditions of the query (i.e., it has a 952 containing a branch subfield whose value is SF and it has a 952 containing the specified acq date), the entire bib is retrieved. The bibliographic search engine is not currently set up to verify that queries on embedded item fields are all referring to the same item record.
