missing orderBy

[tacman]

on https://dexie.org/docs/API-Reference#query-items

// This query is equal to:
//   select * from friends where firstName='Angela' order by lastName
const angelasSortedByLastName = await db.friends
    .where('[firstName+lastName]')
    .between([["Angela", ""], ["Angela", "\uffff"])
    .toArray()

Is it really the same as the orderby? If so, can you document why, or correct it if it's simply missing the orderby. Thx.
