That was one time, when the crew still needed to be gathered. Also, just because she was mentioned before her appearance doesn't mean she will join. Wanna know who else was mentioned before their appearance? Boa Hancock, Iceberg, Marshall D. Teach, and Enel. Did they join? No. By that logic it would imply that Lola's mother is going to be a Straw Hat.
