Can Piercing Light target two units at different battlefields on the first cast (not counting Repeat)?

Ruling: Yes, Piercing Light can target two units at different battlefields on the first cast. The second target can be any unit anywhere that isn't the first unit.

Nuances:

• The targeting choices for Repeat instances are separate and not connected to the first instance
• The second target is not restricted to units in base or at the same battlefield as the first target
