Ok, I checked closely for coyote jumping and it's there and and it's very generous too. I miss-attributed the problem. I went back to the stairs and like I experienced; jumping while running down them sometimes takes away the double jump.
Another weird thing I noticed is that as I'm jumping on the spring sometimes I get my double jump back, also pressing jump as I land can either almost stop the push from the spring or get a super boost that shoots me to the roof! That's a speerun tech that would definitely save time!
