This happens since without the comma, you still have valid Mathematica synt=
ax. That is

In[1]:=
(2*U + L)*P211 == L*P221 + U*P202*(L + 2*U)*P113 ==
  K*P313 + K*P213 + U*P102

Out[1]=
P211*(L + 2*U) == L*P221 + P113*P202*U*(L + 2*U) ==
  K*P213 + K*P313 + P102*U

So, you simply transform the problem from one set of equations to another w=
hen the comma is omitted.
