I do not understand what you say here? Are you saying:
"I can be tricked easier when the order is top-down,
specifically when the more competent developer tries to?"

By reading the code, I think we snap to the first match. And matching
is done via the wildmatch.{c,h}, that claims it has special-case '/' matching,
and '**' **  work differently than '*',
