Your pool, your risk. I wouldn't do it because I know if a bolus of bleach hits the chlorinator there could be trouble. It's not worth the risk.

In that situation it's just about as easy to pour the bleach in front of the return, and it's completely free of risk.

I will not recommend pouring bleach in a skimmer where there is an automatic chlorinator. Period.
