If it had been intelligently designed, you wouldn't be able

it misleads you to think you're going the right way.

The design is intelligent in the sense that it solves a much bigger
problem: left and right hand drawer slides have always been a PITA to
keep track of.

The "mirrored" slides are interchangeable, meaning you no longer have to
worry about matching pairs of drawer slides; and if you buy an extra
pair for when Murphy strikes, you now have two spares instead of one.

No, you kind of missed my point. The design is bad if the lever
can move both ways, but only one has an effect. If the lever can
only move one way, it's obvious when you're pushing the wrong way
because it doesn't move. It's still symmetric, up on one side
and down on the other, but it's user-friendly about it.
