The comment on the return-false path when both UNION siblings are exhausted said "there are more rows," which is the opposite of what the code does. The code itself is correct, returning false to signal no more rows, but the misleading comment could tempt a reader into "fixing" the return value, which would cause UNION plans to loop indefinitely. Back-patch to 17, where JSON_TABLE was introduced.
