It is zassert_true(diff < max && diff > min) meaning _less than_ 1%. The test uses a 1-second delay. When SYS_CLOCK_TICKS_PER_SEC=100 that means a single tick discrepancy would overflow the test. Let's be inclusive and allow up to 1% instead. That allows for this test to pass on m2gl025_miv when using 100 ticks per sec.
