'gotest' is not a kind of goto?

Without goto, then with the form of if-else chain above, exactly one 
branch is expected to be executed each time you enter the first 'if'.

And it will continue execution (subject to break, continue, return, 
exit() or longjmp()) following the final }.

As for the execution path of your example, it's anyone's guess. After 
'if' is entered, more than one block could be executed, and a block 
could be executed multiple times.

Structured programming it isn't.
