Sim.

USB 3.0 also introduced a new Micro-B cable plug, which consists of a standard USB 1.x/2.0 Micro-B cable plug, with additional 5-pin plug "stacked" on side of it.

That way, USB 3.0 Micro-A host connector preserved its backward compatibility with the USB 1.x/2.0 Micro-B cable plugs.

However, it is not possible to plug a USB 3.0 Micro-B plug into a USB 2.0 Micro-B receptacle, due to a physically larger connector.

...

Backward compatibility

USB 3.0 and USB 2.0 (or earlier) Type-A plugs and receptacles are designed to interoperate.

USB 3.0 Type-B receptacles, such as those found on peripheral devices, are larger than in USB 2.0 (or earlier versions), and accept both the larger USB 3.0 Type-B plug and the smaller USB 2.0 (or earlier) Type-B plug. USB 3.0 Type B plugs are larger than USB 2.0 (or earlier) Type-B plugs; therefore, USB 3.0 Type-B plugs cannot be inserted into USB 2.0 (or earlier) Type-B receptacles.
