Well, yes and no.

People might remember that there once was a cafe. They might call the 
building "the cafe" even if its no longer a cafe "in use".

So this is what the mapper *may* wanted to express. While I don't think 
the combination is well done, it but could well have its reasons.


However,

This obviously doesn't work pretty well in the 4th dimension, if you 
want to tag: this once was a cafe, before that a pub, before a bakery 
and before that a police_station.


Another even simpler problem, if a node is tagged:

shop=bakery
amenity=police_station
disused=yes

disused refers to shop or amenity now?
