Not at all.

The pipe uses the left-hand operand if it is defined; a value of None
or an empty string is still a defined value.  As long as "here" can be
traversed with the name "getDataInici" then the left-hand expression
will be used.  If that traversal fails the right-hand expression will
be used instead.

Indeed :-)
