How can the phrase "within the Planck interval, time is wrapped in space" be interpreted?

Excerpt from the book "The Theory of God" by Bernard Heisch."And if we go back almost the same logarithmic interval, we will get to the moment called the "Planck time interval". This interval is of particular importance in quantum physics, because it is believed that at this level time becomes vague. In fact, Hartle and Hawking demonstrated that at that primordial moment when the universe is at its highest energy density, there is still no clear separation between the dimensions of space and time. And if we try to mathematically delve as far into the past as possible, then within the Planck interval, time is wrapped up in space, and calculations begin to lead us forward in time, instead of running into zero."
