Watching the reconstruction gives much better perspective than reading the transcript. Although you can read the timeline in transcript, only when you watch it, you realize how fast it unfold. From the callout "100" to "20" it's only 5 seconds, numbers from 80 to 20 are read with single breath. There was almost no time for any action, especially with hesitation. So it's quite possible, that they in fact didn't intend to bust the minima, and as earlier discussed between them, planned to go around from 100m, but later botched it due to several reasons:
1. They descended to wrong 100m - radio height, not baro height, so they were lower, giving them less time.
2. Excessive descent rate.
3. Incorrect way in which they tried to go around.
Given where they in fact were at the "100" callout, and their descent rate (add to that engines at idle), even if doing everything correctly, it would be difficult to go around. Add to it just a tad of hesitation what to do, and you're doomed.
