Per NRPM 4.1.7  (Section "RFC 2050"):

"ARIN takes guidance from allocation and assignment policies and procedures set forth in RFC 2050."

RFC 2050 states: "IP addresses are valid as long as the criteria continues to be met."

This would indicate that despite the criteria being provided in the
context  of a new allocation, the actual IP assignment or allocation 
remains "valid as long as the criteria continues to be met". 
(I believe I already answered this question earlier on the mailing list, but 
repeat it here in case it is useful in consideration of the policy proposal)
