FSAUtility Changing Modify Date

I am trying to recall all files and replace the placeholders.

In doing some testing, I thought I was good to go. However, I noticed that after the recall completes, all folders have a new modified date/time of when the file was recalled. The files are retaining the older dates, but all folders are not.

Is this normal behavior? I don't want this to affect my backup jobs that have filters not to back up anything past a specific date.
