Remote user connection to Azure Via ExpressRoute

Hello experts,

I just need a validation (I seem to have a mental gap)

For external (not presently on the on-premise network) users trying to connect to a VM in azure on an ExpressRoute Circuit.

1.if they use a VPN client to tunnel into the On-premise network (Cisco anywhere for instance), can they use that same VPN connectivity to get into the ExpressRoute circuit and then connect to Azure?

2. Can Point-to-Site Connectivity work in a set up where you have both Azure ExpressRoute and Site-to-Site VPN?
