I'd say it'd probably be the second one.

You could write: a≶b≶c, which means that either a<b<c or a>b>c.

Or you could write something like: |x|=±x if x≷0.

The upper level is one case, the lower level is the other case.

It is rarely used. Different cases are usually put on different lines with braced conditions.
