That's the standard way to have multiple values for a key in OSM, and it is exactly what I use for dual-numbered PRoWs like that. My Rights of Way progress tool at http://robert.mathmos.net/osm/prow/progress/ knows about this and will interpret such prow_ref values correctly. It will also handle multi-valued designation=* values, for the rare cases where you have two different sorts of PRoWs on the same route, or (slightly more commonly) where a PRoW runs along an Unclassified Highway. (The tool is strict about not having a space after the semi-colon though.) AFAIK, basic Overpass Turbo queries won't find values that are part of a multi-valued tag, but you can do a regular-expression-based query to get around this. For example: http://overpass-turbo.eu/?w=%22prow_ref%22~%22(^|;)Adderbury+FP+1(;|$)%22+global&R looks for "Adderbury FP 1" bounded by either semi-colons or the start/end of the tag string.
