What does the ROC curve look like with TPR = 1 and different FPRs?

Question

Classification

Hello.
I don’t quite understand how the ROC curves will look if TPR = 1, and the FPR, for example, will be different.
After all, if all TRUE objects are defined correctly, the graph will go from point (0, 0) to point (0, 1)?
And it turns out that no matter what FPR, then the line will go perpendicular to Y to the right in any case?
For example , here they build ROC with an explanation. If his most recent object 0 were predicted to be 1 instead of 0, would the graph be the same?
