Without the telekinesis, you'd have 32/16 = 2 times the damage absorbed. So that'd be 120, not 80. The improvement is even greater than you'd said.
EDIT: Except, of course, that, in most cases, you'd have at least 1 point in telekinesis because it's a pre-requisite for energy shield. So the base case with 60% absorb would be 40 life damage and 116.25 mana damage.
