This makes me wonder if it has to do with the OS/driver configuration.
I've always run the trackpoints as PS/2 mice in Linux which is basically the legacy compatibility mode, and I don't use the touchpad. So I'm not running the Synaptics driver at all, and I do remember when I tried using the Synaptics driver on the X250 @ my previous employer it was very frustrating until I got rid of that and got things back in old-fashioned PS/2 mouse emulation mode. I wasn't having problems with drift, it was more click behavior and acceleration curves being very wonky.
But maybe if you're driving things at the Synaptics driver level there's a tighter integration and the OS/driver plays a bigger part in recentering the trackpoint. I'm just speculating here.

They've all been bulletproof used as PS/2 mice.
