Zero Cost Collar

I have a question about Zero cost or cost less collar
Fundamentally it can be used to Freeze your profits or loss for a period

I understand it when applied to a long position but get confused when applied to a underlying short Position
Short Position

Example You are Short ES @ 2000
Es goes up by 20 Pts to 2020 so loss on position 20pts
Execute a AT the Money collar ( don't ask the reason why ATM) costing 3-4 pts
Sell 2020 PUT and Purchase 2020 Call

IF ES then goes further to 2050

SO total move = 50 pts

What would be my situation? at expiry?
