Thank you Paul.
Upon close reading of it, I found this:
"The zones are similar to current requirements in the 16th. Edition except for the omission of zone 3, also that zone 2 no longer extends above zone 1." {Colour change by me: for emphasis}
That would seem to explain the differences in my two pictures: one refers to the 16th. Ed., the other to the 17th.
Moreover, it seems that this zoning change has been enabled by the requirement in the 17th. Edition that all electrical fixtures in a bathroom must be supplied by a 30 mA RCD - if fed from a 230v. a.c. source.
Al.
