Though the high pH (alkaline) of bleach isn't as bad as acidity, I would pour it slowly in front of the returns. It seems to mix rather quickly that way while still being briefly concentrated for a localized super-shock.

One of these days if we understand why SWG systems are so effective, the recommendations for chlorine dispersal might change. For instance, I wouldn't be surprised if we find that it's more effective to add it with the pump off so that it slowly disperses giving plenty of contact time to oxidize the bad stuff you want destroyed in your pool (chloramines, chlorinated organics). Then, after a short time (15-30 minutes?) the pump would be turned on to make sure the residual gets everywhere. That's not a recommendation, just a future possibility. For now, stick with the returns.
