"getApplicableSchemas()" returns an iterable set of all (sub)schemas that apply to the attachment point in the instance.
The use is this:
getApplicableSchemas(ldo.hrefSchema, "/" + varname)
The function use has nothing to do with the attachment point: it extracts from hrefSchema the schema(s) applicable to variable varname. It seems that getApplicableSchemas() should be thought of as a generic function receiving a schema and a JSON pointer and returning the subschemas applicable to the instance value pointed at. Perhaps the explanation should describe this generic functionality, rather than describe the result of its usage.
The explanation is probably not correct:
