Why is Rog hide same as invis/ivu?

[4WOFURY]

Allakhazam link is evidence that hide > invis/ivu, excluding there being any patch post-Luclin stating an upgrade.

As stated, that was written during PoP era with mention of SoS even further improving hide (I used to camp out with Naggy, we were pals after SoS), mention of Vah Shir (Luclin), etc. PoP was only two expansions after Velious, and not a lot of time between the two for a major change like that to Hide without there being a patch note.
