Indeed he did not. However he said that such invasion to annex more of Ukrainian territory does not make sense. In order to run a very expensive and widely unpopular military operation you do need a good motive, and this means that whatever is the purpose of the military buildup, invasion is not the goal.
Russian military did not invade undisputed territories since War in Afghanistan and they now prefer hybrid wars or limited peacekeeping operations, rather than full scale invasions. They may provide some support to Donbas, but there is actually no point even investing in that. Minsk agreements are quite favorable to Russia, so it brings more value to persuade Germany and France that Ukraine needs more pressure to implement them. No, the real target of this buildup is NATO, playing Biden into signing new security treaties.
