Even if IE11 has only “almost caught up”, that means, as you point out, that inertia to change will mean existing users will be less likely to switch away from IE, as alternative browsers will no longer be significantly better. Just that will help to halt any downward spiral.

Note that on Akamai[0] (who have many of the world‘s largest sites as their customers) IE’s share is relatively static. On NetMarketShare[1], IE’s share is increasing. It seems any such downward spirals has already halted. At least on two of the major analytics sites that release public data.
