No,no,no! It is never a directional problem to read from an output!
(The question of capacitance load on the output driver is a separate
question.)
See my bugnote to 1573.

Think of the physical reality. The fact that a gate has multiple fanout,
one inside the module and one outside, does not turn that wire into an
inout. Only when it is driven from outside to inside.
