Yeah this is a pretty odd choice, it would be fascinating to find out Motorola's reasoning.
Motorola was comfortably TI's biggest OEM back when TI was actively pushing OMAP for smartphones. The original Droid (Milestone outside the US) through the Droid 4 were all OMAP (first OMAP3, then OMAP4) and I believe also used TI WiFi/Bluetooth.
The last "flagship" Android phone to use OMAP was the Galaxy Nexus, which had Android updates stop with 4.3. It's been rumored this was because TI had stopped maintaining up-to-date kernels/drivers for use with Android.
This would make it a bigger chore to bring-up the current version of Android than it would be on a current Snapdragon.
Also, the OMAP3630 is just an old chip: 45nm vs. 28nm used by the other (Snapdragon 400) Android Wear watches.
If I had to guess: Motorola had a bunch of OMAP3630s still left in stock (and was quoted a very good price by TI for more)
