Plot points on saved figures in tiled layouts

I'm trying to create a plot with two figures of experimental data (loaded from .fig files) with my data scattered on the plots. The first plot works as expected (figure loads to tile and then points are correctly plotted over the figure, using the same axes as the loaded figure). When I try to plot onto the second figure/tile, new axes are created for my scattered points rather than using the axes from the loaded figure. How can I force my second scatter plot to use the same axis as the figure that is loaded to that tile?

%data from simulation
CD_12 = 0.073319041;
CL_12 = 0.44840455;
CD_5 = 0.017854421;
CL_5 = 0.4961008;
alpha = 12; %degrees

openfig('NACA0012_CD.fig'); %load saved figure
set(gcf,'Visible','off') %don't display figure on load
ax1=gca;
openfig('NACA0012_CL.fig');
set(gcf,'Visible','off')
ax2=gca;
 
figure()
hold on
tcl=tiledlayout(2,2); %create subplots
ax1.Parent=tcl;
ax1.Layout.Tile=1;
scatter(12, CD_12) %plot my data
hold on
scatter(5, CD_5)

nexttile
ax2.Parent=tcl;
ax2.Layout.Tile=2;
hold on
scatter(12, CL_12) %plot my data
hold on
scatter(5, CL_5)

Specify the axis handle in the scatter function,

scatter(ax2, __)
