Nah, you destroyed his soul. In MQ you killed him the only way on nirn possible.
I can't remember whether its a greybeard, esbern or paarthuunax but one of them comments on the fact that you didn't absorb his soul so alduin could still come back

this i think was paarthunax or greybeard the blades know nothing about dragons other than how to destroy them
Since dragons were not eliminated I think that what we are seeing is a knew type of dragon (water dragons) and breaking through the ice is the start of a knew attack (break through the ice and come back up from directly under the PC
It's probably a scripted one-time thing. The landscape for the most part is static, like when you kill a dragon and a scripted fall animation happens that makes a trail.
