Imagine the following scenario:
Skater A has been quietly nursing an injury but plans to compete anyway. She skates the warmup, takes her place efficiently when called, and starts the program. However, within 30 seconds it becomes clear that she will not be able to make through the program. Tearfully, she approaches the referee and explains that she needs to withdraw. There might be some back and forth including about the possibility of resuming at the end of the group, but the whole exchange also takes well under a minute. The skater takes a regretful bow and leaves the ice. (If Skater A is Plushenko in Russia, this might take a few minutes. In most cases, not so much.)
Skater B is called, minutes before she expected to skate.
Is that unfair to Skater B?
