depends on both the man and the woman. marrying a alimah should get the husband more clued up in terms of knowledge. but if the man continually keeps on asking the wife,then i can see how she should could become assertive over time. asking your wife about masail is not wrong. lets just say, you are bayt to a shaykh. now your wife, who is a alimah is not,and unknown to you, she does not agree with the concept. now, if you rely on her for your masail, i'll guess that you will leave the shaykh over time.
