0.999...8 does not equal 0.999...9 so no
If the "…" means 'repeats without end' here, then saying "there's an 8 after" or "the final 9" is a contradiction as there is no such end to get to.
There are cases where "…" is a finite sequence, such as "1, 2, … 99, 100". But this is not one of them.
I'm aware, I was trying to use the same notation that he was so it might be easier for him to understand
