Why can a bond portfolio still lose money after I match its duration to the benchmark?

I thought matching duration meant I was hedged, but one practice explanation said the hedge failed because the curve twist was concentrated in the 10-year sector. How is that possible if total duration matched?

Matching aggregate duration only hedges a small parallel shift reasonably well. It does not guarantee protection if one part of the curve moves much more than the rest.
