The latter.

The overlapping dynamics would be detected if they were in the same
voice.

You are getting a new implicit Voice started for each skip parallelly in
a Staff, while the override is established in an existing voice which is
then continued to be used.

"When should I start a new implicit Voice?" is a question that LilyPond
answers with heuristics that allow it to proceed in a reasonable way for
most cases.

Just not all...
