Cant be true, that doesn't follow the narrative of 100m sea-level rise in the next 10 years

Tucked away in the conclusions is the only reference to the AMO
" Ocean temperatures are expected to rise over the next century (Stocker et al., 2013), which will likely produce further retreat of Jakobshavn Isbræ. Superimposed on any trend for the last century, however, there is substantial multi-decadal scale variability of ocean temperatures in Disko Bay that correlates well with the Atlantic Multidecadal Oscillation (AMO) index, which has been linked to past changes on Jakobshavn Isbræ(Lloydetal.,2011).Thus, whether Jakobshavn Isbræ can stabilize, at least temporarily, likely depends on whether a cycle similar to that of the last century produces an extended period (several more years to decades) of cooler waters in Disko Bay."

So how fast would the freeze have had to be for that to happen?

It's not so much a 'freeze' Naut as the snows that did not melt?
There is an Andean ice sheet in rapid thaw and it to is releasing the vegetation at its base from when those first snows failed to melt out over the summer?

That was my point GW - the snows that didn't melt over the summer. When you see that it is time to decamp equatorward
