Does PicoBlaze have separate flags for each regbank (like Z80), or are the same flags used in both regbanks?

Question

Does PicoBlaze have separate flags for each regbank (like Z80), or are the same flags used in both regbanks? For instance, consider the following code:

regbank a
load s0, 0
sub  s0, 0
regbank b
load s0, 1
sub  s0, 0
regbank a
jump z , success
jump nz, failure

Where will it jump? To success or to failure?
In my PicoBlaze Simulator (it's runnable in a browser, try the "Regbanks-Flags Test" example, the 7th example from the left), it jumps to success. But I am not sure what it would do on real PicoBlaze.
