Plate tectonics is driven by the circulation in the mantel of the earth. That in turn runs on energy from the core, which is a combination of decaying radioactives and residual heat left over from the formation of the planet (and perhaps whatever event created the moon).

250 million years ago there was only one continent, Pangea it has been called, there might once again be only one. But as long as the 'engine' at the earth's core is still running, that too will evenutally break up.

That's how I read the article. That there would be a 'hesitation' following some continental coziness.
