Yeah, because EXPLAIN doesn't show the individual qual clauses attached
to each plan node. EXPLAIN VERBOSE does ... but it's, um, too verbose
for most people.
I've speculated to myself about designing some intermediate level of
EXPLAIN display that would show things like qual clauses and indexscan
conditions in a readable fashion (unlike EXPLAIN VERBOSE). It could use
the ruleutils.c code to produce the output, so there's not that much
coding involved, just some tasteful selection of exactly what details to
show and how to format the output. But I haven't gotten around to
actually doing anything ...
