X: Bob is a doctor (vet)
Y: Bob can prescribe medicine
A: Bob can prescribe Ozempic
“Bob is a doctor so Bob can prescribe medicine. Bob can prescribe medicine so Bob can probably prescribe Ozempic.” (Unsound, but turns out to be fine bc conclusion is about the same as “Bob is a doctor who can prescribe medicine, so Bob can probably prescribe Ozempic”, which is the sound version of the argument.)
“Bob is a vet so Bob can prescribe medicine. Bob can prescribe medicine so Bob can probably prescribe Ozempic.” Now we see why the argument is unsound—it can go wrong given a different premise.

Ok it does seem like an example then. Thank you for spelling it out.
