Top of roots look bad, But they look healthy near the bottom

[Root child]

Hey, so I wasn't really sure where to ask about this so I came here. I've had this phalaenopsis orchid for about a couple years and it's the first orchid I've ever had and I'm beginner so I don't really know too much so excuse my ignorance. But basically I recently re-potted it In this new black pot with bark, previously it was in a very small pot, clinging to the moss. But It was suffering from some root rot so I took away the medium, cut off the dead roots and re-potted it in bark. But I'm also concerned because the top roots look thin and dead but near the bottom they'll still look and feel alive. They kinda look like they're breaking apart and holding onto a plant thread. I'm just wondering if I should be concerned or what I can do to fix this. Any advice would be greatly appreciated.

some more info:
- I previously would only water from the top and it was so small and smooshed I wasn't able to not pour onto the roots but now I've been trying to soak it in water in a bucket
- It's currently winter
