hum... try this:
let mapleader = 'a'
nn <leader>j :ec 'a banana'<CR>
let mapleader = 'b'
nn <leader>j :ec 'an apple'<CR>
let mapleader = 'a'
nn <leader>k :ec 'an orange'<CR>
which work 100% fine here.

Ok, so question closed here.
Notice that <XXX> is surely not completely
defined in compile time, for we use
g:mapleader to set <leader> at run time.
Am I following things right?
