Good morning. Your explanation with visual was excellent. Given HN's stated SAT position, I figure a roll either way gains the a/c access with the Satellite via its dorsal antennae placement.
What would not be conducive to signal maintenance would be (imo) a Pitch Down.
Roll limit in autoflight before involuntary uncouple is 45 degrees. The Pitch Down limit is 15 degrees (9 in PU). With a signal at ~70 to horizon and perhaps 8 o'clock (?), some combination of Roll right and nose down would cut the signal? The cycling in HN"s graph suggests exactly what, to you? In either extreme of attitude, whether only PD or Rolling with reversals, what would the related aerodynamic picture of this signal behaviour be in your opinion?
