AD4002 SDO contention


I'm trying with AD4002 for 18-bit application, one feature mentioned in datasheet looks confusing to me:

"If multiple AD4002/AD4006/AD4010 devices are selected at the same time, the SDO output pin handles this contention without damage or induced latch-up."

does that mean the SDO is open-drain based, given pull-up resistor available for busy mode? How to detect such contention and correct those corrupted bits or even meta-stable ones? i.e., how should we use this feature, or rather be avoided anyway?
