Zygopetalum Advance Australia Roots Exposed/Varied PBulb Heights

[Als]

I just took home a Zygo Advance Australia and I was considering waiting to repot until after it blooms. However, I realized the pseudobulbs are all at different heights so some are buried in the media and one is high above with the roots coming down... Thinking that this might be a terrestrial (or semi-terrestrial??) orchid I was worried that might be a problem, so I wrapped it in sphagnum moss. Was that right?

I would be ok with repotting sooner - but in that case, any advice for repotting when the pseudobulbs are at different heights?

• First photo is my attempt to cover the roots with moss.
• Second photo is what the roots look when I pull the moss aside.
• Third photo is the other side of the plant with the low planted pseudobulb.

Also, I believe the potting material that came with the plant is pure orchiata bark. All the moss in the photo I added.

Thanks everyone for your help!
