Why not prescribe one single meaning and run with it?

E.g. margin in css goes TRBL (yes, another version again :).
For people that cannot cope with that, there is
margin-left, margin-top, margin-right, margin-bottom, but margin is an
abbreviation where the order defines which it maps to.

I just don't understand why we need to care about the way the order is
specified in other systems. People have to adapt their way of thinking
to the context always anyway. One fixed way will make it less
confusing IMO.
