Saturn in OH with other planets

Hi Ernst,

Saturn is in 5th H Aq, with Muntha Lord Mercury, Year Lord Venus, & also Ju (Enemies) 

Saturn will protect its OH & yogas that it makes, yes?

What else will Saturn protect, being in its OH? For ex.g, If there is a yoga between Venus & Mercury, or Venus & Moon (in Muntha), will Saturn protect these yogas that might (for e.g) otherwise be obstructed since Venus & Mercury are in Saturn's rasi? 

Thanks.
