From what I've understood, the collapsing glacier either contained enough liquid water or melted enough from the impact that it continued flowing downstream. It covered ~20 horizontal kilometers in about 7 minutes before hitting the border crossing.

Massive tonnages breaking off of a glacier is still going to be mostly ice on impact .. there's a chance debris and ice chunks made a temporary dam as the bulk of the now shattered glacier ice released water putting pressure on that weak dam - leading to collapse and release.
