For catches in the end zone, the catch process has to be completed. Chase lost control of the ball as his second foot was coming down. The process of a catch was re-initiated, and Chase lost the ball again. He slid out of bounds afterwards. 

This is the most helpful explanation I've seen.  Thanks.
