Eek. I don't get that impression from him at all. Frankly, from Soong's answer to Data's question (In Brothers) about why he'd created him, Soong was almost entirely motivated by preserving himself in his achievements, like by fathering DataThat is an interesting - and creepy - suggestion that Soong was going to transfer his mind to Data or Lore. It does kind of give a predatory slant to his paternal role.
Man, did I ever like Miles & Keiko's relationship better when they weren't main characters. Putting main characters in relationships is usually a loud cry that they got nothing left to write for one or both of them, & whatever one gets no more distinctive plotlines was the one they bailed on. It's lazy writing, plain & simple. I'm actually incredibly pleased TNG steered clear of it on the wholeI've always liked better when romance partners were side characters or guest stars and not main cast. I feel when the main stars get together it's like their romantic relationship overwhelms their professional one and like every story has to be about it now. I feel it's more interesting when the main characters can talk to each other about their love interests but like as side stories to the science fiction.
