Mutlikey index creates a variadic-length offset table in a tuple.
That is a simplest way to overflow it.
Sure, I'll add a comment.

It's just another way to overflow offset table. For example 1.10 does not
have multikey indexes, so only long test will crash it. And perhaps
we'll merge
into 1.10.
There's also a chance that we'll fix
https://github.com/tarantool/tarantool/issues/5085
and multikey test will not work.
