TM's snippet system 'only' inserts something. It only replaces  
something if you invoke it via 'foo' and pressing TAB.
Ad hoc I do not know whether one needs $TM_CURRENT_WORD in a snippet  
but one never knows.
In a snippet one could write  **${1:${TM_SELECTED_TEXT:text}}**

Or even a command à la:

input: selection or word
echo -n "**`cat`**"
output: replace selection

if you don't select something in beforehand.
