I thought that this code was trying to test that AllocConsole had
redirected stdin to the console input, which is usually (but not
always) the case. Ideally there would be tests for exactly which
circumstances cause AllocConsole to redirect or not redirect stdin,
but I was unable to figure out Windows's internal logic here.

Anyway, if it's not important for this function to try to test that
stdin is now the console input, then yes, we can just use the console
input handle directly.
