Although maybe the person doing the mockup is technically minded, because with a BEMU its not ideal to put the power changeover where train is accelerating, so the end points of wires on up and down tracks might be at different locations.
Or maybe the person doing the mockup has no technical knowledge of OLE, and just chose the first option in their file library on the rendering software. After all, the CGI image isn't going to be used for detailed design.
Ideally want to be able to accelerate away from a junction or station on the mains, then use battery to maintain speed. Approaching any junction ideally need the approach track wired few hundred metres so can change system whilst waiting at signal, not having to change system whilst trying to accelerate clear of junction. Raising and lowering pantographs close to mid junction is high risk, and running excessive distance under the wires with pantograph down is not efficient either.
While this would be ideal, on a substantial number of Bi-mode routes where traction changeover takes place the junctions have not been wired to allow trains to pan up before entering the main line. Instead the risk of raising the pan mid-junction is dealt with by lowering on approach or raising after having cleared the junction.
A discontinuous electrification scheme would be better placed to provide overrruns as part of the wider project (where the overheads for the additional scope would be covered within the overall project) than the Bi-Mode implementation, but I'd suggest that if the battery range was so marginal that it couldn't deal with being held at the last junction, it's probably not going to be suitable for long-term operation. Freight would give a better case for providing the facility to pan up while holding, as they will require more energy to start off, but again if freight is expected to be able to operate on independent traction power, it will likely be difficult to justify the additional complexity of wiring the junction over just waiting for the freight to get past the pointwork before panning up.
Although BEMUs can operate where wire terminations were based on shunt limits of electric locos, those historic limits (designed for different reason) are often not optimised for BEMU efficiency. I suspect a few dozen locations need a few hundred metres, (maybe even mile on one track of double track) of extra wiring if BEMU operation is to be optimised
The number of locations this may affect is fairly small, and unless there was other electrification going on that could easily capture the additional wiring, the less-efficient option of just putting the pantograph up or down in the Platform is likely to be favoured.
The only location where historic shunting Limits of OLE are likely to be an issue that jumps out to me is Crewe. Wolverhampton to Oxley depot, Peterborough, and Norwich potentially. But everywhere else I can think of where historic OLE may have included shunting moves has either been electrified further recently so the OLE has been extended anyway, or was electrified more recently for fixed formations and didn't include lots of extra OLE for shunt moves.
