Just because it is coaxial does not automatically guarantee that it is time coherent. If the crossover is anything other than 1st order (or no xover) then it will have a group delay that means it will not be in time together even if the phase is right.
The offset of the drivers also matters. This is why 1st order speakers that have drivers separated in space vertically need to be offset somehow (usually tilted back) so that the acoustic centers are aligned, more or less, at the recommended listening distance.
Tannoys, for example, are never time coherent, despite being one of the pioneers in the coaxial speaker design.
My Odeon horns are time coherent because they have a 1st order filter and the horn is set back in space to time align the drivers.
