Comment 12 for bug 1548480

Per the original report:

"2 owing to a bug in pm-utils, separately reported, the previous hook is run for a second time instead."

Which might have an effect worse than just disconcerting a reader of /var/log/pm-suspend.log.

Anyhow, even if it's not worth it for the remaining 18 months of 14.04 LTS, the means to pay off the technical debt is there.
