I'm not sure what the motivation for that change was:

----------------------------
revision 1.69
date: 2019-03-26 09:20:38 +0000;  author: mlelstv;  state: Exp;  lines: +8 -4;  commitid: NzJPOJHDHtCW7RgB;
touch match_result only on success.
----------------------------

It's clearly not correct.  The "true" or "false" return means "you should use the match_result that's returned".
