Name matching in boarding pass and lounge card doesnt matter. It is not a strict condition for companies like priority pass and dreamfolks.
The staff just scan the lounge card, scans your boarding pass for record, and if the card gets approved, they let you enter the lounge with a smiling face.
In reality - the manager instructed the staff, not to let people enter the lounge without verifying their details. May it because of staff trainning or too much crowd or they simply are fedup of many people trying 5 to 10 cards checking for access (yes, that is how the entry line gets crowded).
