Trait points from levels and other sources are totally independent.
So, in your example, you'd continue gaining trait points as you level up. To have 8 trait points at level 10, you'd have 2 points from levels (every other level, first point at level 7), and 6 from deeds (hard, but I guess it could happen). At level 11, you'd get another point for a total of 9: 3 from levels, 6 from deeds.
