The pink and chartreuse colours were released in AW13. There's no other explanation for the splitting of colours on the site other than some are going on sale and some aren't. Logic would suggest that they're not going to put the new season's colours in to sale when they match back to the new PTJ/PTSS colours, which almost certainly won't be in the sale.
I may be wrong, although I doubt it. Just speaking from experience.
I would happily bet my left testicle that you, sir, are wrong.
