Ok, I guess I have bad news then. lvm2 in jessie is not really hotplug aware. The lvm2-activation(-early).service units run at a static, fixed time during boot. You'd need something like lvm2's lvmetad support [1]. I tried to enable that in Debian today, but failed miserably due to various bugs (already filed 3 bugs today regarding lvmetad). Ultimately, this is something which needs to be fixed in lvm2 and at this point I don't think there is a lot more that I can do from the systemd side. Sorry for the unsatisfying answer.
