As Louie points out below, for reallocations the answer is no. ARIN has 
always permitted the reallocation of a full netblock. The software would 
have errored out if they had both been reassignments.

It is a rare occurance, but would not be too difficult to implement. 
However, it should be noted that this behavior existed in the old 
software, not something that is a result of the new software release last 
year.

That is correct.
