Obviously you can't just grout an internal corner, it has to be siliconed too, as they always crack. 😉
Then why Silicon over something that you know will fail??
It doesn't fail. The grout is there for the colour, the clear Silicon to stop the water. It gives the illusion of being just another grout line, rather than a wider bead of Silicon.

By grouting, you have removed the required room for expansion beans
Im sat in bed with a lemsip
See a lot of internal grouting joints with hairline cracking though.
