You are confusing two different processes, ice sheets flow outward
from some center point in directions of least resistance, apparently there
is a maximum thickness that ice can exist in Earth's gravity.

So outward flow is sometimes a result of added snow and ice, just
the opposite of melting.

Naturally pieces have to break off if nothing supports them, just
how and where they break depends on the terrain and sea level there.
