That's what I meant: The overlay stays with the buffer (unless its
'evaporate' property is non-nil) when you remove the text it covers.
A text property OTOH gets removed with the text and does not stay with
the buffer. Hence a text property is not part of a buffer (or at most
indirectly so) while an overlay is.
