As can be deduced from the name, this property has to do with dotted 
notes and won't affect your example since no dotted notes are involved.
The documentation of this property says:
"Merge noteheads in collisions, even if they have a different number of
dots. This normal notation for some types of polyphonic music."

In your situation, you could do
<<{g8*4/3 fis8*2/3} \\ \times 2/3{e8 fis ais}>>
The g8*4/3 will tell LilyPond to typeset a eighth note but
space it as if it had the duration of 4/3 times its normal lenght,
i.e. the same duration as two of the triplet notes.

If you set the TupletBracket property, there's no need to set also the
tuplet-number-visible property.
In general, when you say \property Voice.property = #value, the property
will only be set in the current Voice context, not in any other Voice
contexts, such as the upper voice when you split into two voices.
If, instead, you say \property Staff.property ..., then the setting
will apply to the full stave. See also
