Macros rule clarification?

I think the wording is pretty clear but I am unfortunately good at misunderstanding basic instructions. For example, I can't have M4 do R-L-R-R-R-R but I can have M4 do R-L-R and M5 do R-R-R and chain M4 and M5?

 

My understanding is that you can have single macros. So M4 doing R-L-R and M5 doing R-R-R is fine. However, you cannot have a single input casting two or more spells in succession, they must come from seperate inputs.

 

Yeah, basically most I can do is have one button for one spell (like M4 for R-L-R), anything more than that is not allowed
(tho u can have multiple buttons like M4 for RLR and M5 for RLL)
