I've been using the tube for 50yrs. In the case of Kings Cross, I
followed the design and building with a fine tooth comb. Here's my
much-discussed guess at the final configuration, long before they
started building:

Yet from the stairs beyond the end of platform 8, labelled Kings Cross
Mainline (ECML) in your diagram, the signs at the bottom of the stairs
direct passengers to turn right for the Victoria Line while turning left is
a much shorter walking route. This is as daft as imagining that one-way
streets reduce traffic.

If every road ran North/East and no roads ran South/West, that would
reduce traffic!

Seriously, some one way systems definitely reduce traffic on the roads
concerned, especially if there are banned turns as well. For instance,
Fairchild Street in Shoreditch is westbound only with no right turn in,
so I have never seen a vehicle using it.
