You are wrong. What do you mean "original h1b"?

Once its transferred, its transferred. There is no "return policy" equivalent because its tied to an employer and your past employer wont necessarily keep the position open just in case you need to come back.

[trustfundbaby]

you have a h1b visa with one company

another company applies to transfer it to them

you continue working at the first company

when the transfer goes through, you give notice at the first company and go to work for the new one

if it fails, you continue working for the first one like nothing happened.

I think you are under the impression that they're talking about the actual H1B transfer failing, but in reality they're talking about the actual new startup company failing. If the startup does fail and the H1B isn't transferred elsewhere again, they do lose the visa.
