Stepped lines

l10n

Can please someone check if these strings are correct? These are from
/help/chart/01.po

<ahelp hid="modules/schart/ui/steppedlinesdlg/step_center_x_rb">Start to
step up vertically and end with horizontal line.</ahelp>

<ahelp hid="modules/schart/ui/steppedlinesdlg/step_end_rb">Start with
horizontal line, step up vertically in the middle of the X values and end
with horizontal line.</ahelp>

It seems to me that ahelp tag is switched. The /step_xx part. Or am I wrong?

Regards
