Hard to say ... a designers choice.

Probably because no one ever tested it and provided feedback. One of the 
advantages of going to tex meetings is that one can then try to convince 
font/macro authors to fix / change.

Anyway, this looks good enough to me:

\startluacode

function document.add_some_characters(target,original)
     local characters = target.characters
     local upper      = characters[0x004C]
     local lower      = characters[0x006C]
     local accent     = characters[0x00B7]
     characters[0x013F] = {
         commands = {
             { "char", 0x004C },
             { "push" },
             { "right", - upper.width + accent.width },
             { "char", 0x00B7 },
             { "pop" },
         },
         width  = upper.width,
         height = upper.height,
         depth  = upper.depth,
     }
     characters[0x0140] = {
         commands = {
             { "char", 0x006C },
             { "push" },
             { "right", - accent.width/2 },
             { "char", 0x00B7 },
             { "pop" },
         },
         width  = lower.width + accent.width/6,
         height = lower.height,
         depth  = lower.depth,
     }
end
