I suspect the idea is to make sure we find out about each episode a week or two before broadcast, whereas with the previous system we found out about some episodes a few days before broadcast, and others over four weeks before, depending on how late or early in the month an episodes airs.

The new way (hopefully) makes the promotion a bit more evenly spread and helps alleviate spoilers - imagine the potential difficulty in having to leave Artemis out of loglines for episodes 8, 9 and 10 had they aired in the same month as Depths.
