It is is working fine here with the layout macro defined inside the loop:

using Plots, Measures
x = 1:10; y = 1:10
const ax = fill(plot(),3,1)
for i = 1:2
   l = @layout [a{0.01h}; grid(2,1)]
   ax[1] = plot(title="Big Title",
      framestyle=nothing,showaxis=false,xticks=false,yticks=false,margin=0mm)
   ax[2] = plot(x, y)
   ax[3] = plot(y, x)
   plot(ax..., layout=l)
   savefig("test_$i.png")
end
