For all you know this may be classic double speak or Al Taqqiya by the Iranians. Use anonymous handles on SM to keep their followers enthused by excoriating India & then use official channels to deny everything.
RN Iranian top leadership is stung by lack of support from any & every quarter. That includes India. They can't complain as well since they were more or less silent in the aftermath of Pahalgham & offered to mediate during Operation Sindoor IIRC - one of our red lines.
If they go complaining to the MEA, the latter would kick their arse. Hence this can be seen somewhat as a reach out & damage control.
