Why do my plots overlap instead of showing up side-by-side?

Explanation: TILEDLAYOUT was written assuming one axes in each tile position. When you create a 2nd (or more) axes in a specific tile position it resets somehow and goes back to first tile position, so they all end up there. Not very useful if you intentionally want to create multiple axes in one tile position (e.g. for multiple X or Y scales).
However the solution is also quite simple... lets first create some fake data:
x1 = [1,2,3,4,5,6,7,8,9,10,11,11,10,9,8,7,6,5,4,3];
y1 = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20];
x2 = [2,5,6,7,5,6,7,10,9,10,11,11,10,9,7,7,7,7,7,7];
y2 = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20];
myb = [0,0.4470,0.7410];
myr = [0.6350,0.0780,0.1840];
Solution: For two or more axes (in one tile position) you will need to manually set those extra axes' LAYOUT.TILE property yourself. I also made improvements / fixed a few other bugs in your code, e.g.
  • replaced GCA with explicit axes handles,
  • removed superfuous AXES calls,
  • simplifed the Y reversal,
  • made explicit references to the axes handle for all labels etc.
tlh = tiledlayout(2,4);
%
ax1 = nexttile(tlh);
plot(ax1,x1,y1,'-','lineWidth', 2,'Color',myr);
ylabel(ax1,'Depth (m)');
xlabel(ax1,'Temperature (C)');
ax1.YDir = 'reverse';
ax1.XColor = myr;
ax1.YColor = 'k';
ax1.Box = 'off';
%
ax2 = axes(tlh); % !!!
ax2.Layout.Tile = ax1.Layout.Tile; % !!!
plot(ax2,x2,y2,'-','lineWidth', 2,'Color',myb);
xlabel(ax2,'Salinity (PSU)');
ax2.XAxisLocation = 'top';
ax2.YAxisLocation = 'right';
ax2.YAxis.Visible = 'off';
ax2.YDir = 'reverse';
ax2.XColor = myb;
ax2.Color = 'none';
ax2.Box = 'off';
%
ax3 = nexttile(tlh);
plot(ax3,x1,y1,'-','lineWidth', 2,'Color',myr)
ylabel(ax3,'Depth (m)');
xlabel(ax3,'Temperature (C)');
ax3.YDir = 'reverse';
ax3.XColor = myr;
ax3.YColor = 'k';
ax3.Box = 'off';
%
ax4 = axes(tlh); % !!!
ax4.Layout.Tile = ax3.Layout.Tile; % !!!
plot(ax4,x2,y2,'-','lineWidth', 2,'Color',myb);
xlabel(ax4,'Salinity (PSU)');
ax4.XAxisLocation = 'top';
ax4.YAxisLocation = 'right';
ax4.YAxis.Visible = 'off';
ax4.YDir = 'reverse';
ax4.XColor = myb;
ax4.Color = 'none';
ax4.Box = 'off';
