I'm not sure what you mean by disguise, and what you expect should have been done. The MIME encoding is legitimate and normal for a header with a non-ascii character, and SA decodes it for header and body rules. The 'B' characters have been overlaid with a clearly visible slash, which isn't very clever in a phishing email.
