A lot, if not all, of these filling loops have integrated double check valves, just like yours (top left valve) that stops the mains from becoming contaminated.
The main reason for removing the loop when not in use is to avoid user interference and extend the life of the loop seals etc. Unfortunately a lot of systems aren't installed/maintained properly and invariably leak pressure requiring frequent top ups and accelerated system corrosion.

Even though the imports had started to arrive, it was only a trickle at this stage and one of the main problems was that a mains water connection to a central heating system was simply not permitted and the use of make up bottles and the like were seen as a poor alternative. A change in water regulations in the 80’s to allow a temporary mains ‘filling loop connection’ to be made to the mains water supply was exactly what the combination boiler market had been waiting for.
