 I'm sorry, I do not follow what you mean here. 
 The mls range for root is s0-s0:c0.c255, where:
 se_sen = s0
 se_clr = s0:c0.c255
 The mls range for mcthomps is s0, given the above works then:
 se_clr = s0
...and given the range is s0 and not s0-s0 then se_sen must be blank
(and so won't match s0).
