We know the Rinnegan powers have a sort of equivalency or trade-off mechanism: When using all 6 powers, what each can do is limited. When focusing on one path, that path gains much more power.

Similarly we know that use of Rinnegan powers has drawbacks, scaling with the power of the ability.

Combining these two, it makes sense that using a power limits the use of other powers. Spamming one type of power limits the use of other powers (equivalency) and using one power to a greater extent increases it's drawbacks. Obito spent all his power keeping 6 jinchuriki and Biju under wraps (whereas Tendo Pain couldn't hold down one) so by these two above principles he couldn't use another.

Madara similarly spammed certain powers (IE Limbo) so he couldn't use others. And it makes sense to me that absorbing one high-power jutsu briefly prevents you from using another.
