RTL Adsense Issue and Adsense Policy

Good day,

I am a little bit confused about number of adsense ads per page and about how to add adsense inside posts in RTL WP.

According to google I can add up to 6 ads per page while I have read a lot of people saying 3?

here google policy:

Google content ad limit per page

Currently, AdSense publishers may place up to three AdSense for content units on one webpage. This includes a maximum of one 300×600 ad unit per page. You may also place a maximum of three link units and two search boxes on each webpage.

If I am not wrong that means 3 Content adsense ads and 3 text adsense ads on one page right?

I have tested it and it works but I am afraid I am breaking the policy.

Also which adsense WP Plugin supports RTL WP Website if i need to insert adsense ads inside blog posts.

Thank you
