iPhone 6 stolen. Did I accidentally cancel my pending data erase by removing account from iCloud too soon?

I lost my iphone 6 maybe 2 hours ago and proceeded to do some damage control by accessing the Find My iPhone feature on iCloud. In the following order in the span of maybe 10 minutes, I turned the iPhone on Lost Mode, selected the remote wipe, and selected "remove device from account." I also called my carrier to make sure the account with that phone is cancelled.

However...my iphone has been OFFLINE the whole time, including the time it was stolen. Since I selected the "erase data" and "remove device from account" fuctions while it was offline, will the data still be removed? I read somewhere that removing the device from the iCloud account might cancel the pending iphone data wipe. Does that mean the thief will have access to my phone and all its files? Or will my phone wipe automatically since I selected the "erase data" function? I just want to make sure the thief won't be able to access any of the data on that phone.

I appreciate the help. Thanks!
