Frequency gaps in MQA?

Did you notice the Youtube video at the end?

Måns Rullgård, in the comments notes:

"Note that the frequencies above the gap are a mirror image of those below it with a slight downward slant. This is because the weak upsampling filter used by MQA lets these images through rather than suppress them as it ought to. Nothing above that gap actually existed in the recording. It is all fake. The 2L recording originally has a high sample rate, and MQA preserves it reasonably well up to 44.1 kHz. If you did a playback and (analogue) capture through a certified MQA DAC at 176.4 kHz (or higher), you'd see similar mirroring in the 44.1-88.2 kHz range."
