AFAIK: There may be other data on the same page that is being written
to, or it might be VACUUM activity replicated from the master. Either
way, the standby is saying it has to get rid of that page in order to
stay within sync delay limits with the master.
See the other reply post you got for the tuning parameters you can use
to tweak that permissible sync delay.
