Is it available to use colon two times in this script?

Hello, thanks for your coming. It is not a big question but I am just trying to know is it allowed to do this such as:

Instance.new(“Part”, game:GetService(“Workspace”)).Name = “test"
game:GetService(“Workspace”):WaitForChild(“test”).CFrame = CFrame.new(0,30,0)

I know that this script is unnecessary and you do not need to do that but I just came up this question while playing the game, is it allowed and available to do it?
