If the top of the saddle is more than 6 inches above the top of the toptube, it's OK. Seatposts used to be shorter, and it was normal to show about 4-5" of post, and not more. Nowadays, sloping toptubes and long seatposts change all the rules.
Fit involves much more than seat height. Bar height and length also play into it. Anyway, you already own it, so if it fits close enough to please you, and you can easily straddle the top tube, who cares what other folks think.
