Not true. You have to engage in a way that signals very clearly you don't really give much of a shit about talking to her, and your social status is higher than hers.
For example, if you're having a conversation with your bartender friend and you need a female perspective to settle a disagreement, and you ask for it without fully "engaging" with her, that'll work fine. Once she's been pulled in you will have to keep hooking her into the conversation with interesting tidbits, but eventually most women will just keep talking.
