It's really clever, and I don't think it screws anything up on the outside. This is a technique I'd never thought of, and I can imagine some interesting things coming from this (though I'm not sure it's a canonical technique or incidental). There are some things to think about, like whether the [inlet~] vector is cleared or if it just keeps the last 64 samples for each iteration of the [until] loop.
My patch will not work in environment using blocksize != 64
but it could be fixed by querying current blocksize.

it could also be optimized with an increase of the subpatch blocksize during the clear process in order to reduce the until loop.

anyway, things can always be more optimized, but I don't thinks they always need to be more optimized.

my patch is not amortizing the cost of the operation across multiple block, but this could be done easily.

Pd-l2ork "clear" works only on pd-l2ork.
my abstraction work on all pd variant.
