  In this paper, we investigate the black hole (BH) spin contribution to jet
power, especially for the magnetic arrested disk (MAD), where only inner
accretion disk luminosity is closely coupled with the spin-jet power, and try
to explain the `outliers' track of the radio $L_{\rm R}$ to X-ray luminosity
$L_{\rm X}$ in two black hole X-ray binaries (BHXBs). Our results suggest that
the BZ-jet and the inner-disk coupling could account for the `outliers' track
of the radio/X-ray correlation in two BHXBs, H1743-322 and MAXI J1348-630.
Although the accretion disk of H1743-322 in the outburst could be in the MAD
state, there is a lower probability that MAXI J1348-630 is in the MAD state due
to its low jet production efficiency. The difference in the inner-disk
bolometric luminosity ratio of the two sources implies that these two BHXBs are
in different inner-disk accretion states. We further investigate the
phase-changing regime of MAXI J1348-630 and find that there is a phase
transition around $L_{\rm X}/L_{\rm Edd}\sim 10^{-3}$. The assumption of
sub-MAD is discussed as well.
