[Match History] Inaccurate Item Purchase Timestamps

Not a bug in the client or game, but in the web match history. I got first blood off a level-1 fight and bought Boots and 2 potions off of it right around when minions spawned, but the match details erroneously report those items as being part of my opening buy at 2 seconds into the match.

I understand the web match history is never totally accurate, but I'd rather not have people assume I was hacking or anything. >.>

EDIT: I think I figured out how to reproduce the bug. I forgot to mention I walked back to base to buy the Boots instead of Recalling. There are a couple other instances in the match where I walked out of base and then back in again, and both shop visits were counted as part of the same buy.
