Re: EX4500 vs. EX4600, spanning-tree?

Here is the Juniper documentation on configuring RSTP on EX4600

https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/rstp-edit-protocols-qfx-series.html

Part way down the page is this

Default

RSTP is enabled on all Ethernet switching interfaces.

It appears that RSTP is enabled on all interfaces so it acts just like the EX4500. Is this the case?
