Excog still terminates after timer:
Grants target party member other than self the effect of Excogitation, restoring HP when member's HP falls below 50% or upon effect duration expiration.
Cure Potency: 800
Duration: 45s
Additional Effect: Increases Faerie Gauge by 10
Aetherflow Gauge Cost: 1

Perhaps though the full effect is what you are referring to?: This make me feel safer they did this incase the excog wasn't going to be enough in the end and they timed it to clem themselves with the excog going off at the sameish time to fully full tank heal themselves.

The fact that it heals at all upon the duration expiring was something added in in 4.2.
