Because sunlight breaks down the chlorine.
If you add it in the morning and the sun breaks it down, you may end up with little or no chlorine in your pool by late afternoon. If that happens you will have very little defense against algae all evening and night, until the next morning.
If you add your chlorine in the evening then your pool is protected all evening and night, and the sun doesn't start working on it until morning. If the chlorine is low or gone by late afternoon and you dose the pool again in the evening, there is very little time when your pool is unprotected!
