TBPO's Scratchpad that prevents the CBB from drowning in his conlangs

Sound changes from Proto-Taric:
1. x, h → ç / _[i iː j] or [i iː]_#
2. v → j / _[i iː j] or [i iː]_#
3. v, w → w / _[o u] or [o u]_#
4. v, w → v
5. x, h, ɫ → h, ħ, ɬ
6. ç, tj, kj, sj, hj, ħj → ʃ, t͡ɕ, t͡ʃ, ɕ, ʃ, h
7. V, Vː > V́, V̀
8. V̀ → V̀V́ / _ħ
9. V̀, V́ → V̄ / word with single pitch
10. ə → ə̄
11. e, o → ɛ, ɔ

Cool, tonogenesis is always nice to see. What is meant by 7. V, Vː > V́, V̀? Does this mean that in words with two vowels, the first vowel becomes high tone and the second becomes low tone? Also same question about 9.

7. Not. It means that short vowels become high pitch and long become low pitch.
9. It means that if /ħ/ is after a vowel with low pitch, a high pitch vowel of the same quality is inserted between them.
