Yep, this seems to mean that we now have contradictory rules that result in a prohibition of primary lithium batteries on passenger flights.
The press release you cited only allows primary lithiums if they are in a device:
" ... individual shipments of properly secured and packaged equipment containing
small lithium batteries (e.g., a laptop computer) still will be allowed on passenger flights. "
While another rule requires that high power lamps have the batteries removed:

"Q Can I carry my dive light on board an aircraft?
A According to DOT regulations which are enforced by the FAA you can if you remove the batteries from the light.
US DOT 49 CFR Part 175.10(a)(23) "With the approval of the operator of the aircraft and as carry-on baggage, electrically powered heat-producing articles (e.g. battery-operated equipment, such as underwater torches and soldering equipment), which, if accidentally activated, will generate extreme heat and can cause fire. The heat-producing component, or the energy source, must be removed so as to prevent unintentional functioning during transport."
