It doesn't really matter if they have talks or not - Turkey cannot join the EU in it's current state, because to join you have to legally fulfil certain conditions and that's enshrined in the very treaties that underly the existence of the EU in the first place.
The EU's hope is that by continuing talks it'll force Erdogan to backtrack, because he simply has to to join, there's no way to achieve movement on that without getting agreement to change the fundamental treaties that underpin the EU, and that requires referendums in some member states. Getting 27 member states to agree to change the founding legal requirements of the EU to allow a dictatorship in would be hard enough at the best of times, much less when you have to get the people of some countries to agree too when there's so much anti-Turkish sentiment at the moment in the EU anyway since Erdogan decided to declare entire EU states to be nazis.
So long story short, talks or not doesn't matter - the point is that Turkey simply cannot join the EU without sorting itself out, therefore the EU is probably in a better place to try and convince Turkey to change track by keeping that on the table, than by taking it off the table which will give Erdogan all the excuse he needs to carry on Turkey's descent into authoritarianism.
So the GP might not be entirely correct but his point remains all the same - contrary to the OP's implication that the EU is about to let a dictatorship in, that simply cannot happen without every nation and a majority of citizens in some nations agreeing to it and if that happens then the EU is basically fucked regardless, because something weird would've had to have happened for a majority of say, Belgians, to accept free movement of citizens from a middle eastern Islamic dictatorship.
