Open Stack

Hello,
Could anybody kindly elaborate on the meaning of a condition in a message:

"The flag which represents condition of reserved resources of the
lease. If it is true, the amount of reserved resources is less than
the request or reserved resources were changed."

The obscure part for me is "less than the request or reserved
resources were changed."

Context: heat/engine/resources/openstack/blazar/lease.py:233

TY!
