The address "O you who are wrapped up! Stand"
Hypothesis examined: when the Qur'an addresses someone with a participle of wrapping ("O you who are wrapped up", "O you who are covered in a cloak") followed by the order « قُمْ » ("Stand / Arise"), the state named would be precisely the one to leave.
Both occurrences are real and answer each other: « يَٰٓأَيُّهَا ٱلْمُزَّمِّلُ قُمِ ٱلَّيْلَ » (73:1-2) and « يَٰٓأَيُّهَا ٱلْمُدَّثِّرُ قُمْ فَأَنذِرْ » (74:1-2). In both, the address names a man wrapped up, then the order makes him rise. Both participles are hapaxes (files زمل and دثر).
But two occurrences, in two consecutive suras, do not make a general rule; and the statement ("the state named is the one to leave") is a reading, not a regularity verifiable elsewhere in the corpus.
The fact has its place elsewhere: it illustrates the learning “Reading a sura with its neighbours”, by which neighbouring suras answer each other in pairs. It is recorded there as evidence.
