Dogasu had a likely explanation of that.
As we know, episodes are written with the assumption they will air on certain dates, and sometimes fit into certain real-life events, like new game releases, merchandise releases, Pokemon event (like the recent Jirachi episode), etc.
Since 2 episodes had been skipped in March, all episodes of the show were shown 2 weeks before they were intended to, and they needed to fix this. As such, we got a special airing of a short most viewers had never seen o kill one of these weeks. Not too long after, a baseball break killed the other week, and from that point everything aired when it had been intended to.
This is also likely the point it was decided to not air those two skipped episodes, hence the need for something else to fill that gap.
