If the attacker has 50+% of mining power for the entire duration then yes it wouldn’t work as the longer things stretch out the further ahead the attacker gets (statistically).
However it the attacker has less than 50% they can still wage an attack. With 10% of mining power I’ve got a 1% chance of mining consecutive blocks. It dwindles quickly even for larger percentages and a large number of confirms makes that angle impractical.

It dwindles quickly even for larger percentages and a large number of confirms makes that angle impractical. ETC's blockchain just had over 100+ blocks change, according to the tweet. Even with 40% of the mining power, the probability of such an event (40% mining power, 100 consecutive blocks) is 0.000000000000000000000000000000000000016%. That's a very unlikely hypothesis you're presenting.
