Yes, they do look like what I'd expect for a trace showing the horiz over the time period of a vertical sweep (and then some). Showing that some vertical deflection energy getting into the horiz (usually not a problem).
The 2nd picture also looks like the scope ground had gotten poor, letting ground loop hum get into the trace.
