m_map m_grid for south pole

Using the similar code when plotting north pole and south pole:

figure ('pos',[100 100 1400 800]);

% north pole
subplot(1,2,1)
m_proj('stereographic','lat',90,'long',0,'radius',50);
m_grid('xtick',12,'tickdir','out','ytick',[50 60 70 80],'linest','-');
m_coast('patch',[.5 .5 .5],'edgecolor','k');

% south pole
subplot(1,2,2)
m_proj('stereographic','lat',-90,'long',0,'radius',50);
m_grid('xtick',12,'tickdir','out','ytick',[-80 -70 -60 -50],'linest','-');
m_coast('patch',[.5 .5 .5],'edgecolor','k');

The result figure as you can see above

The longitude ticklabel for the North pole were showing outside, while the lon ticklabel for the South Pole were showing inside (which is quite annoying)

I was wondering is there any code to change the location of the longitude ticklabe of South pole?

while, I just figure it out by myself

m_grid('FontSize',14,'FontWeight','bold','tickdir','out',...
    'xtick',6,'ytick',[-80 -70 -60 -50 -40],...
    'XaxisLoaction','top',...
    'linest','-','xlabeldir', 'end', 'ylabeldir', 'end');
