Probably just an effort to discourage escalation. They don’t have diplomatic relations so they’re always signalling through military and public statements. Iran doesn’t want a direct war with Israel and wants to go back to the shadow war they’ve been fighting for decades. They’ve been sabre-rattling militarily and pressuring restraint diplomatically since their attack. They’re obviously not going to say “attacking us in a limited way is totally cool,” but I think the takeaway is basically “we won’t escalate if you won’t.”
