carefully note the "or".
If you first move it under ARIN's jurisdiction (by signing an RSA) and *then* transfer it to RIPE, it won't be "legacy" any more in the course of the 2nd step and RIPE's 2-yr holding period comes into play (=> it can't be transferred during that time).

Note also there's voices recommending not to sign an RSA for legacy space (in certain situations, at least), see
