orchid mix has soil in it

[TracyLee9]

I've just repotted 3 orchids for the first time. Two of them were drenched, totally soaked with water (they were tighly packed in moss and clearly not enough drainage)...the other one hasn't bloomed in over a year...and I noticed most of the roots were rotten, apart from the aerial roots.
My husband bought orchid mix from the nursary. There was a lot of soil/dirt mixed in with the bark. Is this ok, or was I supposed to soak it first to get rid of the dirt? I probably should've asked this before I repotted them...now I'm just looking for peace of mind! I mixed it with a little bit of green moss too.
The one with only healthy aerial roots left, I didn't "bury" these in the mix because I read that aerial roots won't adapt well to being "buried" and should be left outside.
Have I done this right or do I need to start again?
Also, I know one shouldn't repot during bud/flowering...but what about new leaf growth? Will repotting shock it too much and stunt the new leaf growth, or can I go ahead and repot these?
