60 day visa from some countries allow non Thai citizens and residents to remain in the country for up to 60days from the date of arrival. Hence it is a permission to stay visa for that period so this information is correct. See it says visa class on the arrival stamp
My question is how do you track a tourist aren’t you touring the country hmmm. Some don’t stay in the same place for more than a couple of days. Backpackers for example!!!
