This is a misinterpretation of what happened and this comment is just weird.
Coal has been added after nuclear was stopped but what you said is not happening at all. Look at the actual data instead of random Internet comments and populist articles by biased journalists:

While lignite was in fact re-added, Germany only slowed the reduction of overall coal power and did not stop or reverse it as constantly proclaimed by commenters who care more about politics than engineering.
So Germany displaced nuclear mostly by renewable energy - WHILE ONLY SLOWING THE REDUCTION OF COAL when they added lignite. So still less coal than before, just not as fast as before.
