Hi Team, When using force push to move and emplacement trooper can you utilize the reposition key word and pivot the trooper?

If Boba plays the card Whipcord Launcher. His free actions says chose a unit at range 1 of Boba and they gain 2 immobilize tokens and 2 suppression. With the wording "at range 1" does that mean Boba can not choose the unit he is currently engaged with as the target of the whipcord, as they are in Melee range not at range 1? The same way a vehicle can not shoot at melee range with a ranged weapon?
