No, that's definitely not right. That wording suggests some kind of
pattern matching, which is not what's happening at all. Evaluation is a
process that takes an expression and produces a value. For example,
(+ 1 2) is an expression that evaluates to 3. The expression is a list
with three elements: the symbol +, the number 1, and the number 2. The
result of evaluating that expression is the number 3.

I agree that the word "consider" is a bad choice in that sentence.
It would be better to change "consider" to "use".
Thanks,
