In brief, the one that works is ismple and direct, and therefore likely to
work, if only because it is simpler to understand. The earlier version twists
in upon itself in unnecessary complication, and such complication in itself is
likely to induce errors/. Specifically here, the inner split probably
generates onelist, and calling split on that list will operate only on the
first item, since split is used to split scalars into lists, and does not
operate on lists.
The principle of KISS operates in the programming field more than in any other
science IMHO.
