For the same reason that in the following:

[c.upper() for c in some_string if 'a' < c < 'x']

having the c symbol not stand for the speed of light is okay. Likewise, 
in the sentence "I went to the park today", the symbol I doesn't mean the 
element iodine. Symbols are context-dependent: the x in one equation is 
not necessarily the same x in another equation, and the symbol = in one 
context does not necessarily have the same meaning as in another context.
