A floor that moonlights as a spelling test between Britain and America.

means One complete level of a building — everything on a single horizontal layer between floor and ceiling.

from From Anglo-Latin historia, meaning 'story' or 'picture-set' — medieval English buildings were sometimes decorated with ranks of painted windows or sculpted scenes, one tier per floor, and each tier came to be called a 'storey' after the pictorial 'history' it displayed. The spelling split later: British English kept 'storey' for the building sense (distinct from narrative 'story'), while American English simplified both to 'story.' The actual link between pictures and floors is debated by etymologists, but it's the leading theory, not folklore.
