The fact that the lines would serve the same northern termini is not a
reason to portray them as the same line, in fact it's a reason to portay
them as different lines. I'm sure the residents and visitors in Uxbridge
would find life more confusing if LT decided that trains from Cockfosters
to
Uxbridge and trains from Aldgate to Uxbridge should be portrayed as the
same
line, as would anyone using Kings Cross, or trying to get from Finchley Rd
to Hyde Pk Corner (just as groups of people can be found every ten minutes
or so on the Northern Line platforms at Leicester Square staring at the
line
map verbally arguing over where Kings Cross has gone.)

Conversely, the Northern Line platforms at Kings Cross have people wondering
where Leicester Square and Waterloo have gone.
