iPhone 5s - what does recents mean in message list and why do only some numbers have it?

I typed in a telephone number to send a text to a new number and as I typed the number it came up with similar ones as I searched. Some came up with recents and had an information button next to them. I'm sure some were deleted numbers and couldn't find them in contacts. I've never seen this before. Is it something to do with the iOS 8 update? The numbers were deleted before then?

i don't believe this is a new iOS feature-
