Documentation, no, but an example seems to support that CEF is *not* going to impose and remove a label: For a route on the same PE, same VRF: router#sh ip cef vrf xxx x.x.x.8 detail x.x.x.8/32, epoch 1 local label info: other/759 recursive via x.x.x.66 recursive via x.x.x.x/30 attached to Serial4/0/0.1/1/3/2:0 Same VPN, other PE: router#sh ip cef vrf xxx x.x.x.121 detail x.x.x.121/32, epoch 1 recursive via x.x.x.56 label 67 nexthop x.x.x.34 TenGigabitEthernet9/1 label 16071 Whether some kind of recirculation happens inside the box where it puts a label on and then takes it off again, I don't know, but I absolutely agree that it sounds somewhat strange.
