In the snippet below (taken from Rosicky, Adamek: On injectivity in locally presentable categories) in the context of locally presentable categories it seems that injectivity class doesn't imply weakly reflective. I'm interested why this reversion of the implication is not elementary true, i.e. why that factorization doesn't give us weak reflection, what's wrong with this intuition here ?
