Myself and wife attended visa interview today and received one blue slip

Myself (h1b) and my wife (h4) attended interview today at Chennai US Consulate. The Visa Officer looked at my wife and said she needs more time to process my wife’s visa application and gave her a blue slip. She did not say anything negative to me. To me she said I will receive my passport before my wife. My question is since we both attended the interview and only got one blue slip does it mean that my visa was approved and my wife is in process or does it mean both of our application is under 221g administrative processing ?
