BIP-69 writes the next about how inputs must be ordered:
Earlier transaction hashes (in reversed byte-order) are to be sorted in ascending order, lexicographically.
However then, within the examples part additional down, it provides an instance of a transaction which, from what I can inform, kinds lexicographically in bigEndian, the standard txid byte order we see in bitcoin-cli, block explorers, and many others.

Am I simply complicated “reversed-byte order” to imply little endian when it truly means massive Endian (as a result of txids are serialized in little endian in transactions)?
