But I don't understand why the attached patch doesn't work.
It's actually quite easy: You need to connect the second outlet of the [pointer] to a [next( message or the [until]'s right inlet as well. Otherwise if the pointer finds a structure first, that is not of type "$1", the until will never stop and Pd will freeze.
However [until] still can be a very dangerous object. In fact, I stopped using [until] for pointer-traversal, because a similar freeze will happen, if you bang the JInextB when [pd score] doesn't exist! And nothing will be able to stop the [until] in that case. A workaround is possible, though: For that, you don't start the [until] through the inlet, but you use the first pointer found by [pointer] to start the [until] loop (with [t p b]). You will have to take care then to not start the [until] several times ...
I attached a version of JINext which does all this and should be pretty save now against accidentally starting the [until] without stopping it.
