Unable to apply separate colormaps and display in subplots

I am trying to display a grayscale image with different colormaps in a subplot like so:

original = imread('cell.tif');

subplot(2,1,1); imagesc(original); axis('on', 'image'); title('Before'); colorbar; colormap("parula");
subplot(2,1,2); imagesc(original); axis('on', 'image'); title('After'); colorbar; colormap("turbo");

However, as can be seen in the result, I only get the turbo colormap in both the images.

Why does this happen? I was expecting the first image to have the parula colormap, and the second one to have the turbo colormap.

You can fix that by explicitly specifying the axes in the call to colormap().

original = imread('cell.tif');

h1 = subplot(2,1,1);
imagesc(original);
axis('on', 'image');
title('Before');
colorbar;
colormap(h1,"parula");

h2 = subplot(2,1,2);
imagesc(original);
axis('on', 'image');
title('After');
colorbar;
colormap(h2,"turbo");
