There is little difference in the maturity of the seed in a split capsule and one that is about to split. At the first sign of yellowing and/or splitting, a capsule can be harvested just as you described. Sometimes waiting too long can cause you to loose lots of seed.
A lot just has to do with the preference of the lab. I prefer to sow dry seed, but many others prefer green capsules. There is just a slight difference in technique. When I started, all the info pointed to green capsules as the easiest. I found this not to be true for me. Plus, sowing dry seed minimizes any risk of virus transmission.
On the flip side, some genera can benefit from harvesting immature seed. Cyps, Paphs, some others can present problems with germination due to vernalization and dormancy issues (and probably a whole lot we don't understand). Taking the developing embryos from an immature seed capsule is one way of avoiding these germination inhibition factors.
