Assuming an ASME standard then yes the center line of symmetry symbol is used correctly.
ASME Y14.5M - 1994, paragraph 1.8.8 and 1.7.1, fig. 1-33
ASME Y14.5-2009, paragraph 1.8.9 and associated fig. 1-35
ASME Y14.5-2018, paragraphs 4.5.9 and 4.4.1 and fig. 4-33
The only real issues I see are:
If this is an ASME specified engineering drawing and Rule #1 is invoked then the parallelism tolerance is greater than the limits of size rendering that specification meaningless.
The two hole features ( 2X dia.9 H7) specified should most correctly be specified to a perpendicular and not a position tolerance. Though position gets the message across.
Hole features should probably have a "thru" indication or show hidden lines in the top view.
