No, the rule is "Please use the original title unless it is misleading or linkabit." That "unless" is critical. I wish we had some linguistic superglue to keep the two clauses stuck together—they always fall apart in shipping and the first bit is the only one people remember.

> The poster must be popular or someone affiliated with the mods, else they would've had their posting rights revoked by now.

Don't assume omniscience! We miss things. Also, we don't revoke posting rights because of titles unless people break the rules a lot.

It is common practice in legalese, and this may be the reason.

The actual post's title was click-baity and the tweet title too long to submit to HN, so I truncated it.
