Dumbo brain freeze

Hi all, having a stupid moment. Come across this today on job. See photo. It's RCD supplying 10mm shower. As you can see the supply side is coming in on bottom load side so to me that's complete no no but what I'm not clear on does this RCD offer any sort of overload protection.....is it actually a RCBO? I've not come across this manufacturer before . The In rating is the current setting of device. Which in this case is 63amp. So is this infact the overload rating....63? Just that I always thought this In rating on RCD's was just the level of current it could safely withstand with out damage but is not actually the rating for overload protection

Is that a new AD range then, I have a few old ADs and they have a neutral fly lead.

I hate progrrss...?

I don't know how new they are, but I installed my first one about two years ago, I think, this lock down has me very confused about when I last did some work.
