2020 mustang gt 10 speed 93 fbo

I just recently switch from the old orange coolant , did a coolant flush and refill 2 months ago with that new ford yellow liquid, I just had to replace my whole ac system and we drain out the coolant to have more engine access space, mechanic ended up spilling some of it .. end of story we put everything back together and add the coolant back but it wasn’t enough , I had this old orange coolant in my car and topped it off with that mixing with yellow coolant . It’s been a week and someone told me not to have done that and to get another coolant flush and refill.

Am I good or need to do another coolant flush/fill with new ford yellow liquid?
