Yes.
match:
alertname: A
severity: critical
will mean that *both* those labels must have the values given..
match_re:
alertname: 'A|B'
severity: 'critical|warning'
will match alertname "A" or "B", *and* at the same time must have severity
"critical" or "warning". And
match_re:
alertname: 'A|B'
match:
severity: critical
will match alerts where the alertname is "A" or "B", and the severity is
"critical".

The bit which shows match and match_re is under "route":
