That's the same impression I got from Robert Arnold when I talked with him about si5s a few years back.

Where SignWriting can be used to be as detailed or as simple as you want, si5s is intended to be as minimal as possible (or so I understand). In some cases, you may not be able to be as specific with si5s as you can with SignWriting. That's an intentional design decision. New symbols are added only if it is absolutely necessary to be readable. At least, that is how I understand the approach.
