Why does this code not deadlock when entering the same critical section 2 times in a row?

Code:
#define _WIN32_WINNT 0x0403
#include <Windows.h>
#include <stdio.h>
#include <tchar.h>

CRITICAL_SECTION Mutex;

int _tmain(int argc, _TCHAR* argv[]) {
	// Initialize the mutex
	if (!InitializeCriticalSectionAndSpinCount(&Mutex,0x00000001)) {
		wprintf(L"Could not initialize the mutex.");
	}
	
	EnterCriticalSection(&Mutex);
		EnterCriticalSection(&Mutex);
			wprintf(L"This should be impossible to reach because of deadlock.");
		LeaveCriticalSection(&Mutex);
	LeaveCriticalSection(&Mutex);
	
	// Release the mutex
	DeleteCriticalSection(&Mutex);
	
	return 0;
}
