I've no idea why they will have done that, but there will be at least one good reason.
Don't worry about people getting connected to FTTC. The fibre cab has the fibre supply and mains power to drive the DSLAM in it. The trench has ducting with copper cable connecting the DSLAM to a new patch panel inside the phone cabinet. Or at least it will have once the job is completed.
The engineer installing FTTC for a customer doesn't have access to the fibre cabinet. He just connects the phone exchange feed (e-side) to the patch panel, instead of to your d-side line. That allows the DSLAM across the road to combine the two signals and feed that back to the panel, where your d-side line is then connected to the panel connector corresponding to the e-side one.
