Restore from Incremental Backup

I am using Acronis Workstion 10 and have started to make incremental backups - sometimes at various times during the day. They are very quick - as are the full backups. I have been testing the software for restores from the bootable media and have the following question.

To inititate the restore I must go through the dialoges for where the backups are and where to backup to etc. I am also given the opportunity to view the individual incremental backup files during the day/s and can point to an individual file as the start point for the backup. I assumed that all files, including the full backup, prior to that point would be included in the backup and they are. I used disk management to format the partition for restore to get rid of all data and create a disaster recovery scenario. I assumed that the data following the incremental file point would not be included in the restore but that has not been the case. I have created test files subsequent to my restore point that are included in subsequent incremental backups and they are included in the restore process. I was under the impression that Acronis would work from the time of the incremental file backwards and exclude anything newer than that point. Am I missing something or doing something incorrectly?

Thanks for any input.
