I know ...it doesn't make sense. But it's a consistent stat. When I sit back sippin' a coffee and try to rationalize it (because the sample size isn't small) I think it's gotta be a couple of things ...
His usage is typically against the other teams bottom 6 and with our bottom 6 and it's a lot of DZone starts. So his job is to basically "get the puck out" and get off the ice. So the other team wins a faceoff throws a few pucks at the net that get blocked or are low % or even if they're higher % they are executed by the other teams pooptiest players that they really aren't that dangerous. He and Kampf get the puck out and on rare occasion convert it into a scoring chance (and end up scoring at a ridiculously high rate).
Eg. since the trade deadline with Benoit on the ice the Leafs have only 16 HDC but have scored on 6. They've give up 32 HDC but only given up 2 goals. It's a short window but all of his stats are kind of like that.
For me ...bottom line is to just use him against the other teams bottom 6. If he's caught out there against the other teams top line (especially without Matthews) we're (frank)ed.

I'd need to probably pay closer attention to his on-ice performance to determine if it's luck, as the numbers suggest, or if it's something he's doing.
Not all HD chances are created equal and not all goaltenders treat those HD chances equivalently either.
A great example of this are goaltenders like Hellebuyck. His big, poised, has an upright butterfly position and keeps his long pads extended outright but has strong leg positioning and an excellent stick to protect his five hole. By comparison, in my opinion, Stolarz is very similar, but his stick positioning isn't as good and his upper net coverage also is weaker - so he plays a lot like Helly-lite.
When you get in tight against a goalie like that and face physical defensive pressure you're generally left with the option to bang at the puck - whack, whack, whack - which can sometimes lead to 2-3 HD chances recorded even though they never had a chance of beating a larger, upright, well poised goaltender. Softer defensive coverage allows for the opposing player to pull the puck back or maneuver it to a better position down low which changes the nature of the HD chance dramatically.
Most models favour the softer, puck-moving defenseman, but they don't do a good job of recognizing how the larger more physical defenseman is contributing to real chance reduction.
Here's some examples: Looking at 205 qualified defensemen since February 1st (picked arbitrarily to consider later season play vs looser early season play) who have over 250 minutes of 5v5 play:
Pionk and Stanley on Winnipeg are #1 and #2 in HD GA% despite being 16th and 33rd, respectively, in chances against/60. Brandon Carlo is 4th and is 158th in chances against/60. Like here's a larger list looking at HD Chances Against and HD Goals Against perecentage in those chances:

Now I can't speak to all of these names, but I would surmise that in most cases you would find people who have decent gap management and/or are strong down low on opposing forwards not allowing to move in/on the crease.
