11th hour update? (from parler)

UPDATE: SCOTUS rejected the TX case because TX filed their case as "motion for leave to file a bill of complaint". However, SCOTUS signals to TX and other states that if they file their cases as "motion to file the bill of complain", then their cases will be heard. So, now we wait for TX and/or other states to file their cases correctly to SCOTUS again.
Can someone explain to me how changing that one word makes a difference?
