When you move the text, the text properties (face is one of the
properties) also move with it.

    1. Put your cursor on a piece of text.
    2. C-u C-x =
    3. Go to the end of the resulting buffer.
    4. You will see text properties (usually fontified t, and a
       font-lock-face-*), overlay etc.

But when you copy the pasted text in to buffer that has font-lock-mode
on, the copied text will usually change colors.  This "changing of
colors", (I believe) happens very fast that it is barely noticeable.
