Giving them more credit than they probably deserve but: when you're solving "by hand" like they are in the show, keeping a known non-match couple together may actually be helpful for interpreting the results of a matchup ceremony because you'll know that that couple didn't contribute to the beams.
That's different, they do that also, but sometimes for the plot one couple intentionally mess those plans because the love is just too big.
