That usually happens when there is a clock controller (e.g. "clocks")
that has multiple clock signals coming out of it. Typically this is for
a clock generator IP within a SoC or other chip.

However for a single board-level clock such as an osc then it is common
to put it at a top-level for that board since these can change from
board to board.

You are correct.
