Children of axes after using yyaxis right

Why does children not include a and how would I get a(only using ax, b or c)?

% Create the axes object
ax = axes();

% Plot 'a' and 'b' using the same axes
a = plot(ax, 1:10, 1:10, 'DisplayName', 'Test');
yyaxis right
b = plot(ax, 1:10, ones(10, 1), 'DisplayName', 'TestRight');
hold on
c = plot(ax, 1:10, 0.5*ones(10,1), 'DisplayName', 'TestRight2');

% Access the children of the parent object
children = ax.Children

children = 
  2×1 Line array:

  Line    (TestRight2)
  Line    (TestRight)

children = ax.Children

children = 
  Line (Test) with properties:

              Color: [0 0.4470 0.7410]
          LineStyle: '-'
          LineWidth: 0.5000
             Marker: 'none'
         MarkerSize: 6
    MarkerFaceColor: 'none'
