Ork Boyz bodyguard question

[Brother Lutheriel]

I’m new to Warhammer so forgive me for asking what is probably a very old question at this point. 
 

On the boyz squad data card you can attach two leaders to a squad of 20 as long as one of the leaders has the keyword warboss. The problem is that only ghaszkull and the warboss model have both the warboss keyword and the leader ability to lead boyz. This means the only way to use this feature on more than 2 squads of boys is to spam warboss models. And I think you can only have 3 of those anyway. Obviously 6x squads of 20 Ork boyz would still be crazy, but you miss the double buffs from leaders on 2 of those squads. 
 

Am I missing something?

It is true that you are limited in the number of squads that can be double-buffed but this is common most factions. For example, Space Marines can add some minor characters to a squad already led by a Captain.

Yes you can only have 3 war bosses (and 1 Ghazghkull )

If you wanted to maximise this rule you could have it on 4 squads
1 with Ghazghkull 
3 with warbosses
 

All with the 2nd Bodyguard slot being another valid character 

The exact wording is " data sheet name" not Keyword so you can have 1 Ghazghkull  and 3 Warbosses.
