No, it says: "You are granted the right to Modify the software for private use only. You may make, run, and propagate Covered works that you do not Convey, without conditions, so long as your License otherwise remains in force."

It's clear they don't want you distributing modified versions. The thing people are getting caught up on is "You may not create, maintain, or distribute a forked version of the software." They fail to define "forked" but they don't seem to have meant an undistributed modification.
