Is LuaRocks rockspec redefines module names using file names?

Is it normal for LuaRocks to ignore the module name in a rockspec, using
the filename instead?
build = {
type = "builtin",
modules = {
apricot = "src/apricot.lua",
["apricot.stuff"] = "src/apricot/seeds.lua",
-- `apricot.stuff` is renamed to `apricot.seeds`
-- when installed as a rock.
}
}
