That would only work on the upstream interface facing the root bridge
where it is expected that it receive BPDUs.  The downstream interface
would be sending BPDUs in that case, and not expect to receive them.
If the topology dictates that one should never expect to receive BPDUs
on such a port (the port should never lead to a root bridge), I would
configure:

set protocols mstp interface <downstream> no-root-port

instead of the "bpdu-timeout-action block".

But either way, I don't think this can be used as a substitute for the
OAM configuration.
