HTC One Dev Edition Recovery/Root Question

I have the dev edition of the HTC One and from what I can read since the bootloader is unlocked all I should need to do is load a recovery image and then boot into recovery mode in order to get root access. However, when I follow the instructions on Team Android's site when it tells me to run fastboot flash sends file writes ok then at next step where I boot into recovery the Phone just boots up as normal.

Any one have any suggestions or see where I might be going wrong?
