If I understand what you're saying correctly, that's a documented behavior:
>From https://perldoc.perl.org/functions/split.html > If LIMIT is omitted (or, equivalently, zero), then it is usually treated as if it were instead negative but with the exception that trailing empty fields are stripped (empty leading fields are always preserved); if all fields are empty, then all fields are considered to be trailing (and are thus stripped in this case). You're not nuts, it's doing what it's documented to do. (I've been lurking this mailing list for a long time, and for the first time I actually know the answer off the top of my head.)
