I don't like it much, but I don't like

 if A then
    V := X;
 else
    V := Y;
 end if;

that much either.

Read the AI. IIRC, parenthesis are usually required, so (if A then X
else (if B then Y else Z)), but the rules for parenthesis are relaxed
in some contexts, like function arguments, so "F (if A then X else
Y);" instead of "F ((if A then X else Y));".

I think so, yes.
