Why is colormap only applied to the last subplot?

Hello. I made a custom (circular) colormap for phase angles. However, in the loop, only the last subplot takes the change. What is the issue in this code? Thanks!

figure
for i = 1:5
    
    subplot(2, 5, i);
    topoplot(double(squeeze(pophmat(timeidx, i, :, 1))), EEG.chanlocs, ...
             'style', 'map', 'electrodes', 'off');
    title(['Pwr: ' num2str(frequencies(i)) 'Hz, 180ms']);
    
    subplot(2, 5, i+5);
    topoplot(double(squeeze(pophmat(timeidx, i, :, 2))), EEG.chanlocs, ...
             'style', 'map', 'electrodes', 'off');
    title(['Phs: ' num2str(frequencies(i)) 'Hz, 180ms']);
    colormap(gca, circular_jet); % Applying the custom colormap to the current subplot
    
end

becase current axes, that you get with gca is the last subplot

But I tried this also with a handle h = subplot(... and the result was the same. Btw, by the last subplot I mean the last one in the whole set (10th subplot) not the second subplot in each loop.

I debugged my own code and realized that the issue is with the topoplot function. After applying the colormap, when it goes to plot the next one with topoplot, it reverses all the previous changes in colormaps because apparently topoplot implicitly applies its own colormap to the whole figure. Therefore only the last subplot avoids the reset.
