kind of. you load the template metaframe as if it is to be a separate uncoupled template, but then you load the sounds which are part of the host project anyway, coupled. Therefore it loads the same sounds twice in different instances of PLAY - (a) the ones you first loaded, which are unconnected and unused, and (b) the instances you loaded while loading the host project.
this is fine because PLAY doesn't reload samples already used elsewhere, therefore the unused instances don't take up any extra memory, with the advantage that this problem is worked around.
