This is unfortunately not the case. See the libatasmart sources for how we determine what to report to the end user (hint: being careful to not report wrong data is key here). In this particular case the attribute you are mentioning has a normalized value that is above its threshold (since 109 > 6) so it's all good. Also not only Pre-Fail (not Old-Age) attributes contribute to the reported "Healthy" evalution of the disk. The fact that the raw value is sky-high is probably just the disk returning garbage (sadly many disks do that) for the raw value. Feel free to open a bug against libatasmart to add a quirk about that. In the future please keep this page in mind http://www.freedesktop.org/wiki/Software/udisks when filing storage-related bugs.
