I am very novice, but that looks odd to me. I would have expected the asc or desc keywords need to go inside the case (before the end). Otherwise you have either:

... order by start_date desc, asc;

or

... order by desc, start_date asc;

This is what I would expect the syntax to be:

# select start_date from show_date
# order by
# case when start_date > CURRENT_DATE then start_date desc end,
# case when start_date <= CURRENT_DATE then start_date asc end;

Or, it seems like you could do:

# select start_date from show_date
# order by start_date
# case when start_date > CURRENT_DATE then desc end,
# case when start_date <= CURRENT_DATE then asc end;
