Question from a low level memory management noob

I am trying to get familiar with some concepts for low level memory management. Coming from python this is all new for me although I do grasp the basics. I was playing around with tensors and buffers and seeing something that I find very strange so maybe understanding why this program behaves like this will hopefully help me understand something new 🙂 the first time I call print(abuf[2]) yields the correct value (2.0). The second time it's a random number. Why does this happen?

`py
from tensor import Tensor

alias type = DType.float32

fn main():

    var a = Tensor[type](100)
    for i in range(100):
        a[i] = i
    let abuf = a._to_buffer()

    print(abuf[2]) # 2.0
    print(a[2]) # 2.0
    
    print(a[2]) # 2.0
    print(abuf[2]) # some random number... why?
