Moth Orchid grooming questions for my plant specificly

[Willahondro]

Hello,

I'm new here, don't know what I'm doing, and sure don't know the scientific name for my orchid. I have what technology is telling me are Moth Orchids, and I'm a wee bit concerned about the one that I photographed and attached to this thread;

Those blooms are big and pretty, but also from the side view, that little limb is supporting all that weight. When the blooms fall off and it's trimming time, where is the best place to trim back to? I'm nervous that the limb will break.

Feedback is appreciated. These are so pretty I don't want them to die lol.
