The ownership of the US and UK versions had split off by then anyway, EMAP buying the UK one in 1997 and Viacom the US version the following year, so not suprising they went in different directions (looks like the UK version did adopt the angled blue version of the logo that wasn't adopted in the US until after the split though- well, it looks like the US version had a couple of different variants of that logo at different angles, in the UK they only used one of them).

Yes, the two versions of that logo look different to me in any case - perhaps the UK just copied what the former mothership did?
