That's a fair point.  *Normally* the error would be something more like: "No RRSIGs were found covering the RRset".  But in this case, there *was* an RRSIG, so it didn't get *that* error.  DNSViz used to complain when an RRSIG didn't align to a DNSKEY, but that was changed because sometimes there were legitimate reasons for that (like pre-publishing RRSIGs as part of an algorithm rollover).  So all we were left with was an error about the RRSIG itself (i.e., name didn't match).  Probably the "no RRSIG" error should be modified to be "no RRSIG for an existing DNSKEY".
