No. As explained in the quoted text, an H-1(b) petition at Microsoft does not usually represent a new employee. Extensions to existing H-1(b) visas (which can be made indefinitely as long as the beneficiary is in the green card queue) are also counted in Microsoft's H-1(b) petition numbers.
If Microsoft ceased hiring any foreign workers for an entire year, it would still have thousands of H-1(b) petitions in that year, to extend the visas of existing employees.
