He specifically calls out Greece as a special case. His comments are directed towards economies which are not like Greece.

Ah. The trusty "No True Scottsman" fallacy...

No, it's not a "No True Scotsman" fallacy. Greece, crucially, does not print its own currency and there was no real lender of last resort available at the time.

It's been a trivial exercise for many years to point out that countries with even more debt than Greece are not going into debt crises for those exact reasons, with Japan as the almost canonical example with its still-low interest rates.

Well, Greece has done austerity. And now their debt is higher than before. You don't do austerity in the middle of a depression.
