cp_csr_fflags bins being hit?

Example of two bins in cp_csr_fflags: wildcard bins NX = (5'b????0 => 5'b????1); wildcard bins NX1 = (5'b????1 => 5'b????1);

But it seems like all tests clear the fflags before executing the instruction: fsflagsi 0b00000 # clear all fflags fadd.s f4, f11, f25 # perform operation Side note, cp_csr_fflags do not have its own generated test as the flags are expected to be raised by the corner values.

So I am confused why the coverpoints are being hit (as F extension was said to be 100% covered). I might just be misunderstanding the coverpoint, but may be something that needs reconfirming?
