WebVTT alignment cue setting keywords

[r12a]

4.4. WebVTT cue settings
https://w3c.github.io/webvtt/#cue-settings

"A WebVTT alignment cue setting configures the alignment of the text within the cue. The keywords are relative to the cue text’s lines' base direction; for left-to-right English text, "start" means left-aligned."

i suspect the second sentence ought to say

"The start and end keywords are relative to the cue text’s lines' base direction; for left-to-right English text, "start" means left-aligned."
