It ought to be fairly clear from both your own and Rodrigo's description that a smart thief (or a dumb one in a hurry to fence the device) would know all of this, so though it's great to have the potential option to locate and recover your device, it's actually unlikely for a number of technical and logistical reasons.
For that reason alone, the choice to keep Bitlocker to protect your data is obvious, since if the thief is smart, he might first try to gain access to your data before wiping the drive, doing this entire set of steps while the device is offline in order to ensure he can't be located.
