Why my email contacts sync between two different accounts?

[Windows Central Question]

I have Lumia 920 and I have both Gmail and Hotmail accounts on my phone. Why my Hotmail contacts are shown on my Gmail when i start typing new message? I don't want all my contacts to be shown there and there is no way to delete them?

I think the contact suggestion feature doesn't only gather its data from the contacts stored on the device but also from addresses you've already sent emails to. This works across all your configured accounts. No idea though why that bothers you much.
