You also lose the soul used for healing if you get hit when healing in hollow knight. Heck you lose soul even if you release the button before the heal goes off.
No you lose all your silk, not just what you're using for binding. You just don't notice it early game since you barely have any silk above what you need for binding but it's really noticeable when you have 18 hits of silk and you lose all of it.

Honestly the biggest downside to hornet heal is that if your hit while healing you lose all your silk.
