It means that if input A is zero that whatever signal is on BSR, it will be ignored. Input A is a higher priority input than the (presumably) bank select register BSR input.

------------------ This is the essence of a one-bit selector. If the enable "a" is 1, then the BSR value is propagated, selecting the Address Bank when BSR is in the "address bank select-enable state", if it is zero, then the BSR value is "overridden" by the "a", and the Address Bank is always selected.
See "selector/demultiplexer/demux/multiplexer".
