His lonelyness could've caused him to let the Flood obtain a Gravemind so that he could at least have interaction with another sentient being. As soon as more sentient beings arrived, he no longer needed the company of the Flood and resumed his duties of eliminating them.
The Monitors primary function was to contain the Flood. Unless, there's an underlying issue that 2401 was having, we'll never know.
My only speculation that I can think of is that 2401 was on the verge of descending into rampancy thus ignoring containment protocol and allowing the Flood to practically take over the Installation. Before completely slipping he was introduced to the Reclaimer - the Master Chief - and then as you said superior, resumed his duties of trying to eliminate them.
