How do I add plots to separate figures using for loops in Julia

I am trying to create two separate figures for which I'd like to add plots to each using a for loop.

using Plots
gr()
Plots.theme(:juno, fmt = :png)

x = [1,2,3,4]
y = [8,7,6,4]

pt1 = plot()
pt2 = plot(reuse = false)
for i in 1:5
    pt1 = plot!(x, i*y)
    pt2 = plot!(x, y/i, reuse = false)
end

display(pt1)
display(pt2)

I'd expect to get two figures as if I were doing them separately:

But instead what I get is two figures with all the plots for pt1 and pt2.

I tried looking into using push!, but the examples I found were making gifs, which is not what I'm trying to do. This seemed like the most straightforward way that should work, I must just be missing something obvious.

plot! can take plot handle as the first argument so it should be plot!(pt1, x, i*y).

Here is the full corrected code:

using Plots
gr()
Plots.theme(:juno, fmt = :png)

x = [1,2,3,4]
y = [8,7,6,4]

pt1 = plot()
pt2 = plot()
for i in 1:5
    plot!(pt1, x, i*y)
    plot!(pt2, x, y/i)
end

display(pt1)
display(pt2)

And here is the outcome:
