This difference occurs only at startup (time 0) and is due to logic within the block that ensures no contention is on the outputs during configuration. After initial startup, any further assertions of sys_reset_n cause trn_reset_n/user_reset_out(AXI) to assert simultaneously. This behavior is expected.
