I see the problem. This has been introduced as of 7.4a.17
Strange, that nobody noticed until now.

commit 2b79bfdeabbbe8f6e5378290c72c770f84796c08
Author: Bram Moolenaar
Date: Sat Jul 13 16:34:32 2013 +0200
updated for version 7.4a.017
Problem:When 'foldmethod' is "indent", using ">>" on a line just above a
fold makes the cursor line folded. (Evan Laforge)
Solution: Call foldOpenCursor(). (Christian Brabandt)

fixed and the one you noticed.
