Hi, I tested your issue in the latest 8.3.4 version. I can confirm that these moves still take away life orb recoil even if the ability is Sheer Force on the Pokemon. However, those moves require specific scenarios to work such as "be called via Metronome, Mirror Move, Copycat, or Mimic, or be used by a Pokémon that gained Sheer Force by an Ability like Trace or Receiver or a move such as Skill Swap or Role Play".

Thanks for your report, will be moves to internal soon.
