Obi-Wan's CE and synergy

does the new Obi-wan's CE stack with the bonus from synergy?
Synergy is a named ability.

Obi's CE grants a direct bonus to a statistic.

That's not a stacking violation.

What is a stacking violation?

1) Two copies of the same named ability.

2) two direct bonuses (not named abilities) to the same stat from a commander effect.
Thought so, just wanted to double check.
