Actually “reflected” doesn´t mean much for photons: they are absorbed and re-emitted.

Isn't that what "reflected" means?

Not exactly.

https://en.m.wikipedia.org/wiki/Reflection_(physics)

For most of the history of the word “reflect”, its meaning was definitely not “absorb and re-emit photons of the same frequency”.
