What is the difference between created and every time edited, created and any time its edited to subsequently meet criteria?

Created:
         
 Evaluate the rule criteria each time a record is created if the rule criteria is met, run the rule, updates to existing records.

Note: With this option, the rule never runs more than once per record.

Created and every time it's edited:
           
Evaluate the rule criteria each time a record is created or updated.If the rule criteria is met run the rule.

With this option, the rule repeatedly runs every time a record is edited as long as the  record meets the rule criteria.

Note: We cannot add time-dependent actions to the rule if you select this option

Created and any time it's edited to subsequently meet criteria:
          
Evaluate the rule criteria each time a record is created, or updated

•  for a new record run the rule if the rule criteria is met.
• for an update record run the rule only if the record is changed form not meeting the rule criteria to meeting the rule criteria.

Note: which this option the rule can run multiple times per record, but it won't run when the record edits are unrelated to the rule criteria.
