Named will continually re-sign parts of the zone as the RRSIGs for a RRset fall due for replacement. Named looks at which keys are in the active state to determine along with the afore mentioned controls to work out which DNSKEYs will be used to re-sign the RRset. If in the past you only had one key type and you now have two, different keys may be used to re-sign the RRset. If you changed policy in named.conf, the new policy will be implemented as the RRSIGs are re-generated.
It looks like you told named to re-sign the zone when there was only one type of DNSKEY key record (or you where unlucky enough for named to check the available keys whiles there was only one active key present) resulting in named overriding the policy in named.conf.
