D8 Routing structure inconsistency

Reading the documentation on the structure of routes, I note that for the “requirements” section, the following is given for “_permission” (and also for “_role”):

You can specify multiple permissions by separating them with ‘,’ (comma) for AND logic or ‘+’ (plus) for OR logic.

This appears inconsistent with the instruction under “_module_dependencies”

You can combine module names with a + (plus) for an AND relationship or , (comma) for an OR relationship.

Can someone clarify where this inconsistency is intentional? If so, then a note on the documentation page would probably be useful for other people coming across this.
