The trick is you have to fool TeX into thinking that both sides of the
logical expressions have the same depth:
\newsavebox{\lhs}\newsavebox{\rhs}%
\sbox{\rhs}{$(\underbrace{Q}_F \wedge \underbrace{R}_T)$}%
\sbox{\lhs}{$P$}%
\dp\lhs=\dp\rhs % <-- fake box depth
\sbox{\rhs}{$(\underbrace{\usebox{\lhs}}_T\rightarrow\underbrace{\usebox{\rhs}}_F)$}%
\sbox{\lhs}{$((P\rightarrow Q) \vee (P\rightarrow R))$}%
\dp\lhs=\dp\rhs % <-- same as before
$\underbrace{\usebox{\lhs}}_T\rightarrow\underbrace{\usebox{\rhs}}_F$
