I think so. When Minato was originally talking about 10 years, he meant it in the sense that Shin would recognize his feelings for him weren't actually love. Shin feels that he doesn't only feel a simple attraction towards Minato but a love that would still be there in 10 years.
10 years? .. what was he gonna say? does he mean that his feelings for minato will stay the same even after 10 years or something??
