From the update notes
•Automatons may now learn the following spells:
Protect (I-V) / Shell (I-V) / Stoneskin / Haste / Phalanx / Erase / Absorb-Attri / Dispel / Dread Spikes / Addle / Regen IV
*Phalanx and Stoneskin will only be cast upon the master.
*Protect, Shell, and Haste will only be cast upon the master and party members.

I guess it's aligned to no maneuver with a chance that it is only casted on the tanking party member.
