I have a problem with Automation in Jira Service Desk.
A customer added several comments on an issue that is reported by himself.
And JSD have a automation rule with transition on comment, like below

When the customer adds the first comment, the issue's status is changed to 'Waiting for Support' (It is expected and normal).
When the customer adds the second comment, the issue's status is changed to 'Waiting for Customer' (It is not expected!!)
Why the second comment triggers the automation that occurs transition issue to 'Waiting for Customer'??
The customer who adds comment is reporter of the issue. I have no idea...
Am I misunderstand about 'currentUser()'??
