Very interesting video. Not so much for what it shows (it's known as a reefing unit IIRC) but the methodical way they have designed it, and documented it.
Note how the buzzer sounds. Unnecessary in actual use but very handy for ground safety. Note unit is self contained. No control or power wiring needed. A straight timer (with the timer amount labelled).
The design seems to be single string, with no 2nd cutter, but I think that's a minor quibble, and in practice I'm not sure how much use a 2nd cutter would be.
If all their work is to this standard they may be slow but their hardware looks to have a high likely hood of of working.

We're still GO for today's test of a cluster of 3 main parachutes at Center Jump.
We expect to take off at about 12.00, but things can of course change due to weather etc.
This is the expected flight path with a recommended place to get a great photo:

So, why didn't the third parachute inflate fully?
Well, to be honest, a human error was to blame. The reefing line that goes around the bottom of the parachute, wasn't routed correctly through the cutter. So even though the cutter activated as it should, it couldn't cut the line.

That had to have been incredibly frustrating. Seems like a fairly obvious mistake that should have been picked up, but then it's easy to solve world hunger from my armchair too.

I have the opposite view. Better to find this potential error in testing than in flight!

We live stream every launch directly from our mission control ship. In this video we show how we have built a solution that can do this, using rebuilt off the shelf networking equipment.
