The bleeder nipple must be opened as you'll never be able to push it in by hand against the air that's trapped behind the piston that you've had pop out. Once the piston is in full contact all around with the internal seal you've created a sealed system again, thus pushing by hand is impossible. Opening the bleeder will allow the trapped air to escape.

After this situation you will have to bleed the system to remove the air and have fluid take up all the space inside the calliper.

Take it right out and scrub it with a scourer and some brake cleaner. Then wash out the inside of the caliper with brake cleaner. Put some brake fluid on the seal or a tiny bit of rubber grease. With the nipple cracked it should go back in by hand.

You might need to remove the caliper completely and work on it on your bench. Sometimes the dust seal comes out and prevents the piston from going back in.
