Simplify puzzle

Why does the first simplification below fail? (Each term succeeds!) Thanks, Alan Isaac
In[205]:= myassumptions = a > 0 && b > 0 && c > 0 && 1 > d > 0 && 1 > e > 0; Simplify[a*b + c*(1  d*(1  e)) > 0, Assumptions > myassumptions] Simplify[a*b > 0, Assumptions > myassumptions] Simplify[c*(1  d*(1  e)) > 0, Assumptions > myassumptions]
Out[206]= a b + c + c d e > c d
Out[207]= True
Out[208]= True
