While the two aren't related, it could still be true that MJO is more significant during an El Nino than in other times.
Let us say that conditions for tropical cyclogenesis are on a scale of 0-10, where 0 means nothing forms and 10 means that a little bit of vorticity over my hot tub generates a tropical storm. Furthermore, let us say that MJO is a +/-1 contributor to this point scale.
When there are exceptionally favorable conditions, like in 2005, (whose overall conditions we'll rate as an 8 on this hypothetical scale), MJO doesn't matter that much, because even when it's in an unfavorable state, it doesn't bring down the score that much and when it is favorable, the "boost" it brings is marginal; there's already so much forming that its added benefits aren't really noticed.
However, in an El Nino, where overall conditions rate may rate 1,2 or 3, MJO becomes a big deal, as it can have a >33% effect on the score.
While, the numbers, of course, are made up, they do serve to demonstrate that anything that adds to favorable conditions is more significant the less favorable conditions are.
